Image is rendering. Watch it go:

(background is a scaled 160x120 render, rendered tiles are overlaid there)

holy crap, man! This is amazing! Did you put dispersion there? Not that I
care, but...
"Boinc Admin"? :))

No I didn't. Want it for the next render? :)
I should really work on some dynamic tiling, even if I have to set the
tiles by hand. It's annoying when the square at 0,0 (top left) takes 1
second, and other tiles in the middle of glass objects take 10 minutes
or more. It should be for example one big rectangle covering all the
non-glass background...

It's done. I'll put the tiles together.
My initial estimate (by extrapolating render times of smaller
resolutions) was it would have taken 12 hours on my computer alone.

... I find it amusing that the longest thread of the year so far in
p.b.i is titled "waste of time!"

One of the users who rendered some tiles commented "so that what I just
wasted my CPU cycles on?". So you got the thread title exactly right.

huhuhu. That was very kind of you, dude. Thank you very much.
Indeed it'd take about 12 hours. My render of it was at about 9 hours
when I had to go to work. Besides, those lines visible in the joints of
splines...
it's a waste of time, but glassware always looks damn good! ;)

Typo. I wanted to put 1.03. Anyway, 0.03 is a valid value, even if totaly
unrealistic. It's a very strong dispersion where the red is more affected than
the violet.
