I'm going to change floor, make nicer sky, and maybe visulise light_sources 
(using media).

All comments (alsow 'negative' :), are welcomed

Nice, but it needs some anti-aliasing.

btw, 100MB memory used isn't much. My current scene uses about 250. I've had
a scene that used about 700MB (see machine, see machine eat swap file...)

That looks really cool.  Those relected photons on the floor form patterns
that remind me of some fractals and IFS's that you can generate using a
program called Atriatix.

Go for it.  It looks cool how it is, but It might be neat to have a HF for a
floor, or have it look like it's resting on a piilow.

pillow - yes, great idea :) I must try it - maybe there is some function 
looking like pillow in functions.inc ?
