    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.

using the double-arrow operator (-->>) to generate Gray code and visit vertices of a #cube in order -- #d3 #perspective

u/yonatan

you could use the straight-leg-kick operator (--/) and save a char
u/f8f82804

I figured that the community would appreciate seeing the counterpart of the more common single arrow -->
u/magna

When I'm not sure what I'm doing, I use the wiggly arrow operator <~~

Attempted remix of d/7495!
