Ive been getting more into my Kinect hacking recently and watched this video as a source of inspiration of what you can do which the kit. Awesome work and kudos to the crew that worked on this!

Love this stuff.... Trapcode 2 is a plugin for Adobe After Effects that allows you to simulate particles physics. Its pretty powerful and Ive used Trapcode V1 before but you need to have a pretty heafty machine behind you to process anything heavy weight or video intensive.

short experiment with trapcode particular v2.
