Stochastic Progressive Photon Mapping is an extremely interesting rendering technique. It is in the same league of MLT/BiDir Path tracing (i.e. some time even better, some time worse). Anyway it is vastly superior to simple Path tracing. (Stochastic) Progressive Photon Mapping related papers are:

Oh, I'm just splatting the first photons around, I'm still far from a complete PPM (the Stochastic version will arrive later):
and after few seconds:
I enjoying looking at photons bouncing around and splatting colours over the surfaces
