I've had a reasonably successful show with my camera tracking Tetris game. No crazy tracking libraries, just a scan of capture.pixels[] with a 4 step jump and then return the brightest column of pixels (we give the player a white chef's coat to wear). A hot tip for you all is that capture cards combined with a video camera are very good for the job. We used an Osprey one (would retail about £80) and unlike the webcams I've tried it has zero impact on the performance of Processing. Ran in conjunction with the opengl library it gives you some super sexy results.

Just a quickie question about the capture list. I want to put this game's source code online after my show closes tomorrow. But I'd like to have it downloadable as an application, just so people can plug in a cam and play without having to port in 5 tabs of code and look at the longest list of global variables I've ever written. (Things were getting pretty annoying sifting through the classes so I just wrote a huge list of static final variables for my settings.)

Would I be able to use the capture.list() to make a device selection menu? I'm guessing the String it delivers could give devices to use with split(). Likely a need to catch exceptions too. Plausible? Please tell me what you think.
