Lucky you. Nothing can beat the flavor of a well-made coffee.

Huh? hmm er... truly I hoped nobody would notice this :-)

A blob.

Hmm it's not the case. The render almost came to a halt at the last lines,
near the edge of the upper part of the oven (send a ray... reflect down...
reflect up... reflect down... reflect up... repeat as many times as you can
(trace_level 25)... multiply by blur_samples... uh and don't forget about
radiosity... ouch!). I resumed the render today: after four lines at 20 PPM
it rendered reasonably fast.

>May I ask you what radiosity setting do you use?

It's not about particular radiosity settings, it's about tuning some of the
main params of the scene.
I started with a classic:

   radiosity {
        pretrace_start 0.08
        pretrace_end 0.01
        count 300
        error_bound .1
        recursion_limit 2
        gray_threshold 0
        media on
        normal on
    }
Recursion limit 2 is needed as I don't want the most hidden parts of the
scene to look black.
Then I played a while with three parameters:
brightness
diffuse value of the white walls of the kitchen (hidden to the camera)
brightness of the skysphere.
I will play with these a little more later (I'm not completely satisfied of
the result) but here's what I'm using now:
brightness 2
sky_sphere_pigment_multiplier = 2
walls_diffuse = 0.5 (higher values make it look a little washed out)
Of course you need a standard size French window to let the light pass
through.
Hope this helps.
