    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.

wow! here's a 103 byte version if you want to add color or something: w=1920;h=1080;f=()=>Math.random()>.5?10:-10;t?x.fillRect((b+=f()+w)%w,(g+=f()+h)%h,10,10):(b=w/2,g=h/2)

Looks like this dweet is getting "awesomed" a lot due to an exploit in another dweet
