For 81byte slow running version lose the subtle camera waving, drop multiplication from t and the last AND operation from height function :)
u/p01

That makes it 77bytes if use a single for loop with a width of 64 and increment of 1/64 ;)
u/Batrachus

Someone should use this for a black metal video. Even the resolution is perfect.
