    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.

Very rough gears. Don't try this at home.

u/tomxor

With an arrow function there is enough space for some tapered gears :) g=(a,b,n,r)=>{ then i-=d,i+.05)
u/tomxor

Arrow function seems to need a space after the } though !
u/somebody

c.width+=0 and replacing d with .1 directly saves two bytes. might be able to improve the tapering or something
