    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!!!
u/BirdsTweetCodersDweet

What's up with that weird comment at the end?
u/jylikangas

B.J. is the main character from Wolfenstein and in the demo he is obviously lost. Thus the code is properly commented. :)
u/cantelope

looks familiar :P https://www.dwitter.net/d/2961

Torus at the Discoteque

u/rodrigo.siqueira

I am inside a #torus. It reminds your previous #d3 https://www.dwitter.net/d/8707 and also this rotator https://www.dwitter.net/d/13254
u/jylikangas

I did this from scratch and managed to implement a torus in much smaller space than last time. Notice the little ghost effect trick. There's still 22 bytes left but I felt the demo was ready.
u/ivylab

Whoaaaaaaa, so nice, I love this. Futuristic. Motion blur too. Great job!

Training spread syntax and Path2D with Hercule Poirot. :)

u/zanella

Wait, how did you call .join without parentheses?
u/jylikangas

That's ES6 stuff - I'm passing the function a template literal by using back-ticks

Hmm, that's a neat trick.
