    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.

Replace "t" by "(new Date()).getTime()/1000" for real time. No idea how to reduce the rest by that much though.

u/Agnes

Also, the approximation of -2*pi is bad and probably de-syncs the clock after a couple of days.
u/fourier.space

Just like a real clock would!

Point

u/tactical_retard

It takes two random points on a circle, gets the mid point between them, then draws the line connecting them with a color based on the X and Y of the mid point.

You can save 1 character by putting arc(650+250*i,700-i%2*434,r/2,z=i*2.095,5.235+z) in the for loop before stroke()
