I am sorry about confusion, I meant "set_at" not "set_mode".

Is the "set_mode" method faster than the "fill" method? Maybe I should make a test unless someone knows.

I corrected some missing features and mistakes. Hope it works now like expected. It is still rather slow. Looking foreward for good comments :)

Oh, I see. Yes, mod 256 makes sense. You might want to add something like map(int,color) though so that the colors are all integers (actually I would go int(round(function%255)) for each color component). Other than that, optimize. I'm not sure how you would go about it, but seeing as you locked the surface and whatnot, I'm thinking the improvements should be to eval(). ;At the cost of an extra dependency, you might be able to do something with surfarray. I would recommend psyco, but it actually slows it down by ~50% by my tests.

Geometrian, thank you for commenting. I'd like to do that optimization you recommended. I use the mod 256 to keep values valid. I would like to know, why you think width and height would be better. It is good to know that the outline is defined as HTML, thanks :)

I played around with this a bit--it's pretty neat. I recommend optimizing it. A 1024x1024 render takes a looooooong time. Also, maybe the mod operation should mod w,h instead of 256? You can use HTML's <br> to get new lines in the formatting here.

What is the matter with the outline? How to make lines? They figure on the "View" page but here not. Wondering.. :x
