The "fish tank demo" [ie.microsoft.com] that rogerd mentioned is available online, if anyone wants to compare browsers with it.

It uses the HTML5 canvas element to draw the swimming fish swimming. The FPS count tells you how many frames per second the browser is able to draw, and it uses a png sprite approach to create the needed images.
