    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.

My favourite version (over limit): t=t**0.5;with(x)for(i=30;i--;t>2?fillText("debian",670,1e3):fillRect((r=70+80*t*t)*S(m=5.6*t+i/80+t*i%1)*.9+1e3,C(m)*r+390,9,9))fillStyle='#d15',font="14em'"

That one works if you remove the fillStyle ¯\_(ツ)_/¯.
