u/joeytwiddle

I perceive movement inwards, but the code says the only movement is up and down! 🤯 Want proof? Try growing i slowly with i=t*3|0. Or try reversing the movement with t-i/3 instead of t+i/3.
u/joeytwiddle

This is also a rare-ish example of inverted Moire, by which I mean the interference patterns which most stand out are white rather than black.
u/joeytwiddle

The remix simplifies the effect, making it a little easier to see what's happening.
