VNTZ | Event Listings 31 July, 2015 at 4:37 pm

For a long time now there has not been a decent resource listing events in Sydney. InTheMix had officially shut down its WHATSON section. Time Out, Resident Advisor, and even SPRACI are currently hopeless, and Facebook keeps you in an information bubble where you can only see stuff you are more or less directly connected to (eg by invitation, and now Facebook is limiting the number of invitations people can send to their own list of contacts!). What is one to do?… Roll your own!

VNTZ is my contribution. Currently a simple website with links to events pages elsewhere (could be any site, but currently linking to public events on Facebook).

Link submissions are made by simply posting a link to the corresponding VNTZ Event Listings page on Facebook. Easy peasy.

Reach out and touch some…thing – SubPixel / Studio Kanzen 25 November, 2009 at 12:02 am

The following is copied from an email addressed to Studio Kanzen, creators of SubPixel – a digital culture video blog.

Studio Kanzen,

this evening I discovered someone/something called “SubPixel”. My sister asked me what videos were mine on YouTube, saying that she did a search for “subpixel” and found something that looked like porn, so didn’t open it at work. Something about a guy with his shirt off and a girl with her hands somewhere near his groin. “No, I don’t think I have anything that looks like porn, or anything with a guy with his shirt off.”

What was she talking about? YouTube. Search.

I see… SubPixel: Clone a Willy Penis Mold Kit Review

Quite amusing, but no, not one of my videos.

Hi, I’m subpixel. I’ve been pushing pixels under that name since 2002 when I started taking club and party photos for Australia’s dance music community at InTheMix: “sub” as in music, and “pixel” as in pictures (digital photographs). On later reflection it occurred to me that the name had other interpretations, such as “subpixels” meaning “images from a subculture”, or “subpixel” being the thing (or person) underlying/behind the images I was capturing, especially since I was responsible for the images and rarely “in front of the camera” in my own photos, or those taken by other photographers in the Sydney scene.

After being an InTheMix photographer for a year or so, and having made many new friends along the way, I was more inclined to go where some of those friends were going, and less inclined to take on ITM photography assignments elsewhere, though still continued taking photos, including as “official photographer” for an underground party called Undercurrents, and today have an archive of some 70,000+ images and short video clips. I was without a camera – I mean a camera I cared to carry with me, since, now I think about it, I did actually have at least one other – for about 6 months two years ago, and found that to be a bit depressing. That slowed me down a bit, and I don’t seem to have been taking as many since then (or perhaps for a while before), though do go through spurts on occasion.

Photo madness in decline, I am still behind the pixels nonetheless. I acquired in 2003, and continued to use the name, especially for creative projects. In 2006, after a late night laptop-and-video-projector good times retrospective for a friend’s farewell at a city fringe music bunker (another friend’s house with a killer sound system and wall to wall wax) in Sydney, I was asked to supply visuals for a live electronic music gig called Laptopjam, and so the subpixel name moved on to be my VJ moniker.

I appeared mainly at live electronic gigs, VJ meetings and house parties in Sydney until I was roped in as resident VJ for a fledgling club night (Mind! Reggae Dubstep) in Brixton by Italian DJ Unity Selekta along with Earl Gateshead [Trojan Soundsystem] when I moved to London in 2008, strangely enough from my Gumtree listing looking for a place to live. Around the same time I discovered a local VJ community, VJlondon, where I made friends, had fun, and through which landed various gigs around London including a couple more live electronic gigs. I also joined the sizeable contingent of VJlondon crew appearing at LPM 2009Live Performers Meeting – in Rome, apparently the only Australian representative. Through Dr.Mo, who organised most of the VJlondon gatherings, I met architect and artist Alex Haw of atmos (currently working on the CLOUD for the 2012 London Olympics), with whom I collaborated to realise the Weather Projection installation at the inaugural Smart Light Sydney festival – me, a Sydneysider, scrambling to write the code in London (and in Rome after LPM!), and Alex, a Londoner, scrambling to put together the hardware (and content) in Sydney – such a mixed-up world we live in! Unfortunately I wasn’t able to make it to Sydney to see the result, but I’m back in Sydney now, and have rejoined forces with the live electronics party/promoter Midi In The City as well as taking up residency with the closely related TECHnique crew for their monthly techno parties and festival vibes at the Earthdance Sydney 2009 Campout. I have just completed another international collaboration, this time with Venetian producer and deepindub netlabel founder, Maurizio Miceli: a “VJ clip” for Way Out [DIDVJ002] to promote his latest EP.

You can find clips from and information about past VJ gigs at SPXL.TV, and other stuff like my blog including experiments with Processing at

Sourcemap 20 November, 2009 at 3:44 am

Sourcemap – Open Supply Chains

An incomplete Sourcemap for LPM 2009 in Rome, Italy.

Data is based on the artists list on the LPM site.

This Sourcemap was started as a Travel Map and saved, but when attempting to re-edit the map, the “passengers” have each been converted to 97kg of cargo. It would be nice if the map remembered that these were supposed to be human passengers (eg 1164kg is a bit mysterious!).

sIFR fonts delivered by

What is this about?.. A neat little service allowing you to use any of over 1000 freely available fonts for the heading elements on your website by means of including a line of “code” in the <head> section of your page. Sweet beans. :o)

It works by using Javascript to replace each heading element (<h1>, <h2> and so on) by a little box of Flash. If Javascript or Flash is unavailable, the original text/font is displayed. Win-win!

For some reason, just recently I decided to see if was available to register, and to my surprise found that the existing registration had recently expired. What luck! Only… I wasn’t able to register it immediately, as the registrar was holding it in some unusable state (assumedly to allow time to milk some extra higher fees from the existing registrant) and I was told to try bidding for it on some other domain auction site. I don’t know what the details were for using that site – a minimum bid of something like $60, but what exactly would that get me? Maybe the domain… I don’t know. What I do know is that since then some (apparently) Chinese domain squatting company has nabbed it, and seeing prices bandied about in the $100k range for similar domains I wasn’t inclined to make further inquiries. I did notice that was available, though, and the temptation took me… some credit card details and so on later and it was mine. Who needs vowels anyway?

New site coming soon:


Gallery back online 2 February, 2009 at 4:27 pm

For some number of months (the numer itself unknown) my galley has been offline. I was rather concerned that the days (weeks?) worth of tinkering with it, loading gallerys, editing meta-data, etc, had been lost in some abysmal database screwup.

Today I used my web host’s autoinstaller to create a fresh gallery to make some comparisons, to see what’s what.

I enabled a debug setting and was looking at another page for a while and discovered a response indicating that connection to the database had failed. I don’t know the eact cause of this – the database did exist on a server, and I was able to view/administer it through the control panel, but maybe it wasn’t accessible via the “local” php script(s) forming the gallery.

I took a backup of the existing database, created a brand new database, imported the backup, updated the gallery configuration settings with the details of the new database and, hey presto!… my gallery is back! Joy!

I suppose now I should do something about it not containing any new photos since September. :o)

So, what made me come to be tinkering with this now? Well, it is snowing here in London now, as of yesterday – a few inches at least I reckon – and I wanted to share a few photos.

Stay tuned.

Esfera mod by spxl 6 6 January, 2009 at 11:16 am

Processing sample: Esfera_mod_by_spxl_6

based on Esfera.pde by David Pena

Source code:

On Thursday 18 December there was another meeting at Cafe 1001, and again there was a triple-head setup with three projectors onto the back wall of the main room. Nice!

I’d decided that this time I’d work on this Processing sketch to have some 4:1 content for the massive screen. Up until this point, the tentacled object in space had been stationary and not especially interesting-looking. On Thursday morning I started tweaking the program with a view to actually being able to VJ with it, adding a bunch of new features like being able to move it around, make it bigger (“zoom”) or smaller, and more easily change some of the parameters. The tentacle shape changed a bit, as well as the appearance with some new oscillators to change the red, green and blue of the colour, and some mystery 1’s and 0’s on the surfaces. I’m no expert on lighting yet, but at least I managed to do something about it being so dark (as appears in Esfera mod by spxl 5).

I was perhaps a little too engrossed in what I was doing, and at some point realised I was already running late for the gathering!.. and rushed off to Brick Lane with my still warm code. The setup at Cafe 1001 was improved on last time, with a large table for laptops, etc bhind a raised bench with the projectors on it.

The tentacled space thingo was quite well received by the crew, though at that stage it was a bit of a beast to deal with effectively. Having pointer and keyboard inputs, I plugged in my Wacom and handed it to Rob to move it around while tapping at some controls myself on the keyboard. Even at 1920×480 it seemed to run pretty fast (and so it damnwell should!), and with the ultra-widescreen had a nice spacious and spacey feel about it.

I also tried running the radial gradient array sketch at that resolution, but, being a 2D pixel-based affair, my machine just wasn’t fast enough (or rather the program is too intensive) to get above a crawl instead of scintillating flashing colours.

Nevertheless, both sketches have been updated since then, and the Game of Life sketch created, and I’m starting to get a bit mental with trying to put nice comments and such on everything as well as make improvements and add new features. I think the commenting is taking as much time as anything else!.. and of course generally tidying things up, rearranging files on the webserver, updating all the past blog entries with Processing sketches to have a consistent look, and so on. I think I should really investigate creating a plugin or filter or something for WordPress – maybe a little database to keep track of the sketches and format them all nicely. I’m already running in to versioning issues, and changing the structure of the files is bad news for old blog posts!

Yesterday I did some work on creating a better timewarp effect – rather than change the speed of all of the oscillators, instead manipulate the “number of milliseconds” that have passed (this value is used in calculations by the oscillators) and also modify things like how far the object moves or rotates for the frame. Since the program was using simple easing logic, I’ve fudged it by multiplying the easing factor by the square of the (less then 1.0) timewarp factor, or leaving it alone if the timewarp factor is 1 or more (making the movement “faster than the mouse”, as it were,  seemed like a bad idea).

You see the brighter patch of red on the top-right of the sphere in the screenshot? That’s caused by five point lights just near the sphere arranged around the funnel of text. unfortunately the Java applet doesn’t seem to play on my machine (nor does version 5 of this sketch), and I think the lights (or use of lighting generally) is what causes it to fail. Then again, I don’t actually know, so this is only a guess! If you have the PDE installed you should be able to recreate the sketch from the source files.


Go, go, Google Gadget 23 December, 2008 at 7:18 pm

Just above this there should be a “Google Gadget”. This is, of course, just a test.
