Inspired by the Femto-photography experiments at the MIT, I was thinking about reproducing this effect in Blender. I realized that it wouldn't be possible with a Ray Length node based shader alone, so I tried to replicate indirect light bounces by using a particle system shooting out a million of "photons" which are illuminating surface only when passing very close or hitting it. After that I combined all frames to produce a final image of global illumination. Think of it like animated Photon Mapping. I guess with this, I found the most cumbersome and inaccurate way to simulate indirect lighting, but it's fun to watch anyway.
