    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.

c.width=innerWidth is a great idea

(c.width=innerWidth makes it work in fullscreen and not-fullscreen. Thanks to Balint Csala for the trick)

This is based on d/5423 and the amazing bitmap renderer d/5233 by u/RomanW.

This earth is backwards! I think you want S(t+i) and C(t+i)

u/p01

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.
u/sigveseb

Wow! ACE

u/lionleaf

Amazing!
u/Teijou

Does it JS or another language?
u/fusty

Wow . . . how?
u/fusty

It would be amazing if you could post an expanded, commented version along with your 140 character versions on this site.
u/oldspork

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?
u/hg

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.
