Move you mouse to attract the particles. They will leave a color trace on their way. Click to clear the canvas.
Another implementation of having one particle for each pixel of a bitmap. Hold mouse and move.
Combine 3000 particles, a blurfilter and a new gradient colorpalette to create some nice explosions. To be implement into games.
Some particles can move phreatic in space, where small distances between 2 particles create an attraction force. Interact with the mouse.
Tested the performance with AS3. About 9800 Particles are rotated in 3D space. Hold Mousebutton and move to rotate.
