    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.

Global variables can remain defined as you edit if you remove the declaration. So it could be working locally but then break when you post it. Missing a declaration of m :)
u/lionleaf

It's a bug :|
u/lionleaf

Waaaaait, nevermind. It gets initialized when I hover my mouse over the dweet. I was a bit too quick there.
u/Galaxtone

Yah, I do that all the time
u/Galaxtone

Plus I already did that with a and b
u/Galaxtone

I just deleted it and fixed it
u/Galaxtone

So yah:
u/Galaxtone

Ignore the m is undefined error, Just move your mouse inside the dwit to make it go away.
u/sirbo

why do you assign m=e and don't simply use e

Turns out approximations of pi are fine if you're not multiplying with your bad approximation of pi.

Ooops, code blocks seems to be broken at the moment. Don't worry, they are stored correctly in the database, will get fixed at some point

Zamboni simulator. Numbers were chosen to work with Chrome emojis. Probably breaks with any other set of emojis; sorry about that.

Just realised there may be a way cooler way to do this with shadowBlur.
