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.
Even less words, but looks a bit better (to try it out, paste this into a dweet that uses a canvas -it doesn't seem to work otherwise): r=Math.random;a=['man','dog','house','box','fell','walked','on','through'];b=n=>' '+a[n+~~(r()*(n+2))%2];z=e=>r()<.5?' the':' a';x.font='7em"';x.fillText(z()+b(0)+b(4)+b(6)+z()+b(2)+'.',0,t*9e3)
