    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.

You can change the controls by editing 'dsaw' to any four letters, starting with whichever is to be "move right", going clockwise
u/donbright

the controls seem a bit unreliable on my sytem (firefox linux) but when it works, it is reaally cool, one of my favorite dweets ever. nice

font='9 em sans' also works :)
u/nonce

@donbright great tip!
u/cantelope

'9em x'' seems to do the same thing as '9em sans' ¯\_(ツ)_/¯
u/donbright

this reminds me of an old carnival ride in my home town, it was called Phantasmagoria, no longer in operation, but you would ride thru tunnels of glowing pillar-gates. good times. nice job
