    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.

best dwitter torus?
u/sigveseb

nice!
u/keithclark

Why not use x.fillRect((k-a*i-b*a*j)*z+899,(i+b*j+a*k)*z+500,6,6)? it renders faster and is smaller
u/mxfh

Print and connect the dots. Or do it on screen for lasting impact.

SPACE INVADERS

u/Polyducks

Weird... I wonder why it's stopped working...
u/magna

It still works for me. macOS + Chrome.
u/joeytwiddle

MacOS and Chrome here. The unicode char (was it 👾?) appears to get stripped while loading. If I paste it in between the "", then it works. Perhaps Dwitter loads differently on different pages?

u/magna

I was expecting this to happen one day...
u/magna

Wait. How the hell are you rendering the "ground"? I don't get it. Explanation please.
u/nystrand

It's the "(O" chars at the beginning of the code decreasingly scaled down from the large initial scale. I had to find a variable name that "looked good", - went with O which made coding confusing as it looks like a zero :)
u/magna

This is nuts!

Didn't know yours when I did mine (https://www.dwitter.net/d/6216), but yours is waaaay better than mine - I tried to do the dots in the radar and couldn't figure it out. :) BTW, kudos for using the "space" inside the x.beginPath call, great idea!
