    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

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.

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

Clicked random and remixed the first dweet

I clicked random and this was the first dweet, thought it would be funny to remix although I'm not very good at it
