    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.

I worked hard on this one, I hope everyone enjoys. I recommend you at least use this to export all your dweets and back them up. ✌ #dwitter #tool

u/BirdsTweetCodersDweet

You probably meant c.width=480;x.font='150px a';x.fillText(document.getElementsByClassName('score-text')[1],0,180);for(i=48;i--;)x.drawImage(c,i*10,5,10,260,i*10,5+S(i+t*3)*5,10,260) but for some reason the array is undefined... :/
u/BirdsTweetCodersDweet

Well, empty, rather... Anyway, I give up. But span.score-text is not an element - it's a class "score-text" of the parent "span"

Have fun integrating your functions from a to b. Use Math, but not my fault if you exceed the 140 chars ;)
