    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.

PoC for bypassing the char limit

u/joeytwiddle

I am a little bit tempted to post some of my old dweets that couldn't fit ^^
u/pythech

Tbh I too thought about it, but as a new user I didn't have good dweets that couldn't fit ¯\_(ツ)_/¯ Would make a better PoC
u/pythech

The bug is fixed now unfortunately (see github). All the opportunities for me putting a good show are gone
