I a gave presentation at Dorkbot Sydney (24/02/2009) on the Eyesweb Visual Programming Language. It was an overview that exemplified some cool things you could do using live video, iPhones (with accelerometers), mrmr, OSC, and multiple Eyesweb nodes on a network.
(If you're keen to see the detail in the video above, I recommend clicking on the link and switching to High Quality in the Dailymotion player.)
If anyone is interested, I can post the source code for those patches.
