Cats Circling Cats Fourier Transform

See inside
Notes and Credits

Draw any pattern you want on screen, and have it approximated by cats circling cats circling cats....
Written mostly in ApuC so I didn't have to spend so much time dragging blocks out and debugging. See the stage for the ApuC source. (This is probably the first project I have ever made where ApuC worked for its intended purpose - implementing fourier stuff was trivial but it expanded to a huge mess of scratch blocks :P)

Press these keys (I was too lazy to make a gui):
1: Draw a pattern
2: Calculate Fourier coefficients
3: Render approximated function
4: Start/Stop cats spinning animation
5: Reset screen

Start with 1, draw a pattern, then press 2, then press 4.
Adjust the sliders when the animation is playing. The sizes of the cats in the animation correspond to the amplitude of their oscillation.

Note: The cats aren't exactly circling. I didn't bother to correct that.
There are probably more efficient ways to calculate Fourier coefficients. I literally just integrated f(x) f(x)sin(nx) and f(x)cos(nx) 100 times.
