    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.

Shouts back to Xen - this is really a minor tweak on his idea.

Move the mouse around to change the patterns

This borrows from Firefly #1629 again for capturing mouse movement, and combines my previous two dweets.

nice, tried: hsl(${t*s+( ?
u/AliYil

You mean hsl(${t*s+(-j+i) ? Looks good for a few seconds, then hurt my eyes afterwards lol

s=S(t/8.5)*n is a little nicer but I'm still experimenting before another remix.
