    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.

saving more space if you only use the numbers: ".012578"

u/corruptio

instead of 7/32, 7
u/corruptio

/6.4 and 9/6.4 give interesting digits too

It sounds good enough with 200 instead of 99 but +1 over

Fantastic job! Love the use of the cos(t-i) aka backface culling as alpha value of the fillStyle to sort the splats and skip clearing the whole canvas. That was THE killer optimization to fit in 140 chars.

I'm completely new to all coding and just found out about this amazing community; how on Earth do these symbols code for a globe?

oldspork These symbols are just what unicode decides his binary data can best be represented as in text. The real magic is the charCodeAt part of their code.
