    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.

Nice!

Nice one! #globe

I use 44 longitude lines so the arc angle between adjacent two is 2*pi/44 which is approximated by 1/7 to 4 decimal places.
u/pavel

Using the famous pi ~ 22/7 approximation.

Nicee
u/Ath0r

Thanks! It's the first time I've tried, so probably I missed a lot of tricks to reduce characters... Any feedback or tips are welcome! :D
u/13thptr

b is unused so you can remove it :)

Thanks a lot for the suggestions, @13thptr! Indeed, I forgot to remove the unused b and the characters you remove by avoiding the definition of p is also very nice :)

It's a spinning simplex!! :D great 1st dweet

I don't think this actually uses a perspective transform...
