Thank you

I have been doing gi with glsl scripts for a while but my method is a bit "different". Here are some examples:

These are between 64 and 128 ray casts per pixel.
It is using a very simple method to determine a probable direction for each ray bounce (importance sampling) and then determining the amount of light energy left after the bounce (a perfect reflection loses no energy, a diffuse one colors it). The rays are followed backwards from the camera into the scene and only stop when they run out of energy, go out of bounds or hit a light.
If you are interested I can post Fragmentarium code for it. This is a different (simpler) scheme from my earlier gi efforts which were biased towards the light.
