Hi!
This is my implemention of Voxel Cone Tracing. It simulates the first bounce of indirect light. Some artifacts are still there but it’s surprisingly fast on such a high resolution. The scene is small and injecting the light into the voxels is fast. There are many things left to implement though. 
(I hope the video is working! :# )
I’ve never heard of that technique before (any chance you could link to an online paper or site) but it looks impressive (video worked for me as well!)

Good explanation and a bit mathematical
Cheers - just goes to show that Codea can actually be used for some real research & development projects and is NOT just a toy!
Very nice, awesome work!
