blender 3d ftw. The colors on the cube just suck because it's supposed to be whacky for the lighting around it. As you can see, the texture affects the surrounding light.

Well, jim carrey, you can look at the documentation first, and also, to do this specific kind of lighting you need a new build of blender (can't be found on the official homepage) and these builds are on www.graphicall.org. But you have to find the right one, called kai's blender. But of course, this can already be done with something else called radiosity, and that is available in the latest stable release.

I'm a bit lost at what this is supposed to be/do.

but the quality is good.
