Yes, as I thought, no radiosity in SunFlow as it now stands, so there's no light "bounced" off of reflectors, walls, etc. (Supporting such effects wasn't a trivial 6task -- at least, it wasn't the last time I was playing around with ray tracing. There ain't half been some clever algorithms devised since then, though.)
Note you can see the reflection of the illuminated reflector panel in the red light domes on the robot's head.
