    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.

Rhea wanted the rain to be purple. Took a few months. I present: some purple rain.

I had some hard work to use only 140 carac ... nice golfing dude :)

Does anybody know how to make this actually bounce off the sides in 140 characters?
u/BirdsTweetCodersDweet

Better resolution if you want : for(c.width|=i=999;i--;x.fillRect(M.min(1870,M.max(0,960+400*S(a=t+i/4)+800*S(t))),M.min(1030,M.max(0,540+400*C(a)+400*C(t/3))),9,9))M=Math

Great!
u/davidsharp

@Xen, you should totally fork it, that looks great
u/New_Core

on Xen's version can remove t+i to i ... no need to spin it if it looks like a line.

I thought I'd see if I can calulate PI in 140 chars. Math.PI is 3.141592653589793, which is 15 decimal places. 15 decimal places is precise enough to calculate the circumference of the solar system (including Pluto) with an accuracy of a meter. The formula is Nilakantha's from the 15th century. You could also just print 245850922/78256779 but doing that doesn't seem much better than just printing Math.PI.
