Hi Marcus,

try upping -ps. Default for rpict is 4.
You might also wanna reduce -aa, and increase -ar and -ad. There's some 
splotches on the walls, possibly due to caustics from the appliances.

Don't seem right as in no penumbrae? That's expected for a solar source 
modeled with the SOURCE primitive. AFAIK these sources are immune to -dj 
and -ds anyway. Maybe a Fully Licensed Guru[tm] here can tell you more.

Btw, that's a big-ass microwave! :^)
