Precomputed Radiance Transfer publications from the main inventor / proponent of the method

realtime global illumination technology

Nice looking demos of advanced realtime 3d topics. Should be a great source of sample code.

VERY useful color conversion formulae

Quoted: The math used to convert RGB and color data between different color spaces.

random number generator, if you happen to need precalculated random numbers.
Not sure if you can specify a distribution (e.g. Gauss, Poisson, etc) yet.
Nope, you can't. Uniformly distributed only.

Quoted: RANDOM.ORG offers true random numbers to anyone on the Internet. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs.

wow. image editor with layers, all web based (flash)

Quoted: Splashup is the only full-featured, free range, image editor online. Create new images, edit existing images and manipulate layers with filters, layer effects and myriad other drawing and image editing tools.

Cool interactive animations

even cooler pulsating spheres depth of field effect! :)

this is a cool 3d depth of field demo! in a browser! neat effect
