    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.

That's a really clever illusion, love it
u/magna

Heh, thanks! Brought it down to 123 chars in hopes of adding occasional mistakes like skipped characters / typos etc., but couldn't immediately find a way. In case anyone wants to give it a shot: https://www.dwitter.net/d/2522

u/Polyducks

Could you make a random function to skip odd spaces?
u/magna

It has to be a deterministic PRNG so that the places that are skipped are persistent. Otherwise, it would just look like a random flipping of characters. I thought about it, but couldn't immediately find a short solution.
u/Polyducks

That's a great point. Dwitter is such a mind twister!
