HTML5 Canvas Particle Example
Here’s a cool particle demonstration of the HTML5 <canvas> tag. It’s a tremendously small amount of JavaScript code that is responsible for pushing some radial gradient particles around a canvas. You can check out the source code to see how things are done – it uses jQuery a bit and the demo itself uses a free color picker control.
The demo works best in Firefox. Chrome has some ugly rendering artifacts when the gradients cross over one another and Safari can’t push a lot of particles on the screen without dying, but Firefox can render several hundred particles with ease (Internet Explorer doesn’t support <canvas> at all). If the computation for this demo were to be done on a GPU rather than a CPU, you’d probably be able to pump out thousands of particles with no issues.

Worked fine on safari for me – really great canvas demo. Love the way they bounce off each other!
