Sombrero function. Added +j (in fillRect x coordinate) to add perspective. Changed -64/+64 ("for i" and "for j") to other intervals so it can fit the image better and also removed .7* multiplications to get more space for equation.

Sculpture based on torus equation #torus - Animated version. Please come back in year 2029 to see 60 FPS version. I'm getting only 2 FPS now and according to Moore's Law (performance double every 2 years), in about 10 we'll hit 60 FPS.
