    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.

nice!

Thanks. A little too fast, should have been t/8 instead of t/4...
u/aemkei

Thought the same. t/8 is really a calm beauty!

Yeah, my screen does 30Hz so I only notice it when exporting to a gif.

How did you come up with this?
u/iverjo

@badthai: First I made a classic tunnel effect (like this: https://www.dwitter.net/d/205). Then I made several remixes of it by tweaking parameters. This was one of the results. See also https://www.dwitter.net/d/106
