    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.

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

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 :)

Great stuff.
u/CalSch

Cool! I think it would look cooler if it was at a higher frame rate. Is the frame rate low because of the style? Or is it a performance issue.

To any remixers, you can drop the "c.style.background=R();" from the start and you will have 24 chars to play with.
u/katkip

Nice
u/katkip

Not really u/spaceman, on upload, the canvas will be reseted to white
u/spaceman_blanc

yeah youre right, didnt realise that. I mean you could still do something cool with 24 chars and white back ground i guess

The base code draws a tube. 1/S(i%h+h/2) radius makes the tube have a square cross section.
u/pavel

(Y*Y<8e5||Y%1) randomizes the radius between 0 and 1 near top and bottom.
u/pavel

Err, between -1 and 1, and this makes the top and bottom panels.
u/cantelope

I see some gathering of points in the middle of the top and bottom panels, but other than that, a faithful reproduction. kudos!
u/pavel

I use polar coordinates, even though the radius is uniformly random that results in more dots near the middle :/
