    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.

got my mods under 140, yay.

although this 151 has a nicer effect. c.width|=c.style.filter=blur(${1-S(t*6.3)*4}px)contrast(9 x.scale(80,99) for(i=2;i--;x.fillText(~~v%10,9,9))x.fillStyle=R(0,v=t+i/2,0,T=.5-C(v*6.28))
u/BriSeven

even more appealing c.width|=c.style.filter=blur(${.5-S(t*6.28)*12}px)contrast(12 x.scale(80,80) for(i=2;i--;x.fillText(~~v%10,9,9))x.fillStyle=R(0,v=t+i/2,0,T=.7-C(v*6.28))
