    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.

spirals. zoom in, i couldn't fit in a transform

u/tactical_retard

x.setTransform(c.width/s,0,0,c.height/s,0,0)
u/jellyedwards

c.width=200 does a similar job, good work!
u/KilledByAPixel

you could also do x.fillRect(X*9,Y*9,9,9)
