Dwitter - javascript demos in 140 characters

function u(t) {

c.width=1920 // clear the canvas
for(i=0;i<9;i++)
x.fillRect(400+i*100+S(t)*300,400,50,200) // draw 50x200 rects

    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.

#FizzBuzz in 44

u/SockTaters

This is a little refactored, but u/DaSpider's solution also works in 44 characters with just the t|=0 trick. A slicing solution is also very close at 45 char: t|=0;throw'FizzBuzz'.slice(t%3&&4,t%5?4:8)||t
