    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.

It work as a math.floor. actually there is a difference but i dont remember how exactly

u/noonat

~ is a bitwise not. It flips all the bits in the number to the opposite. Flipping again (~~) puts the bits back to what they were. It works does something similar to floor because it truncates floats to 32-bit integers as part of the operation. (But unlike floor, ~~-2.1 is -2 instead of -3.)

How did you come up with this?

@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
