    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.

Let me know if you find a better way to keep the "fly" within the canvas. (Other than 4 if-statements i mean)

u/reportbase

You should use fillstyle to vary the color a little i think.
u/Artfarnaa

You can use C instead of m.c.
u/donbright

t?x.fillRect(a+=9*S(d),b+=9*C(d),9,9):(b=a=99,d=0) d+=Math.random()-.5 d=b>1080?3:(b<0?0:(a>1920?5:(a<0?2:d)))
u/donbright

that will free up 30 characters. line split before d+ and d=b
u/joeytwiddle

Nice compass movement! I like don's if?then:else but i think his (parentheses) can be left out
u/joeytwiddle

An alternative is to wrap around: fillRect(a=(1920+a+9*S(d))%1920,b=(1080+b+9*C(d))%1080,9,9)
u/z3vin

this is so frickin' cool! combo of joey n dons 96 chars: t?x.fillRect(a=(1920+a+9*S(d))%1920,b=(1080+b+9*C(d))%1080,9,9):(b=a=99,d=0),d+=Math.random()-.5
u/Woodmouth

Thanks, that looks really good. Still looking for an actual boarder though, just because of how cute it is when it keeps bumping into the wall.
u/Woodmouth

Ohh, nvm, Donbright does that. (I was just looking that the combo)
u/New_Core

maybe a x% less chance going the direction against a border the closer it gets to it could make a nice pattern. (just an idea, dont know how to do it)
u/donbright

nice work @joeytwiddle is correct abt my parenthesis
