JaVortex
JaVortex is (to quote) a gravitational attraction particle engine NBody simulator, created by Anthony. Put simply, the demo involves lots of particles attracted to each other and the position of the mouse cursor. As they move around the screen, they leave colourful trails.
Cool vortex, ja?
There are various settings to play around with, including the number of particles and whether NBody is turned on or off. With NBody off, the demo will go much faster,and allow for many more particles.
