Sure, at MIT building interactive LED-powered disco dance floors is a good way to decorate your dorm and procrastinate. But, Chris O'Shea of pixelsumo
reminds me, for the designers at Lightspace, it's serious business.
Clearly, the MIT students' DIY project was directly inspired by the
Lightspace team that's . . . wait a minute . . . headquartered in
Cambridge, Massachusetts. Guess there's just something about Cambridge
that makes people want to build elaborate digital disco dance floors.
(See Chris' post on Lightspace)

Lightspace's interactive floors respond in subtle and ingenious ways,
which is why small children are so fond of them. (And, as we've learned
in the past on CDM, small children love heating up dance clubs.)

VJ Fader, creator of Max/MSP/Jitter-powered Neuromixer (an excellent
video mixer with lots of support for controllers), now introduces a
first: VDrum is a step sequencer not only for audio, but video, too. The first version was released today with the following features:

• Sequence AV clips using on/off switches, via numeric pad or MIDI input
• Record video and audio to hard drive
• Multiple resolution support (as in Jitter)
• Audio and video effects
• Midi support

VJ Fader is looking for sample content to include, so contact him if you're interested.

Windows XP only for now, but the other software is cross-platform so this may be, too, very soon.
