Needs more golfing to add an animated wave

~~(Y/3)%2 can be shortened to Y/3&1
u/magna

(X-Y)%4 can be shortened to X-Y&3
u/magna

Added some waves (not so nice): https://www.dwitter.net/d/2188
u/scottglz

I had figured out Y/3%2 before I saw your comment, but X-Y&3 eluded me. Thanks!
u/recursive

I added some different waves. https://www.dwitter.net/d/2196
