Screen captures of a fast particle system with interaction. There are anywhere from 2k to 128k particles on screen at a given moment, all running in real time.
Vimeo’s compression almost completely destroys this, I recommend checking out the Windows Code:Blocks project and compiling it yourself: http://code.google.com/p/kyle/source/browse/#svn/trunk/openframeworks/apps/demos/BinnedParticleSystem It’s way faster than downloading the 270 Mb source video 😉
Inspired by a binning particle system from Zach Lieberman http://www.makingthingsmove.org/blog/?p=251
