http://shadertoy.com/ http://shadertoy.com/ uses GLSL (or whatever its WebGL equivalent is). Is that what you're thinking of? (The language is syntactically similar to C, but quite different from it in some respects, as it compiles to code that runs directly on the GPU. GPUs have a very different execution model from a CPU - though they have been moving closer together and I guess that trend will continue. On the plus side, the performance can be excellent, provided your PC has a decent GPU.)
