    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.

I love this so much, just changing the 'i' multiplier gives drastically different results :D

Yeah, I have an endless remix chain on this lol. Not to mention it's not even shortened slightly bit
u/pythech

Maybe we can mix it with different things or make more advanced animations and so on. It has room for that

Aaand... I just deleted it accidentally, great!

Wanted to fit a thicker line width in but I didn't see a way to. I think it looks okay anyway.

u/DirtyDan

Inspired by: https://old.reddit.com/r/GeometryIsNeat/comm…
u/pythech

it is possible, remixed it with the thicker lines
u/pythech

the trick is x.lineWidth
u/DirtyDan

Yeah, I just couldn't fit it in 140 chars

Tried to create a random city map. It doesn’t work as intended but is still nice to look at. ;)

Peter de Jong attractor. Changing the 1, 2, 3, 4 multipliers in the sine/cosine functions changes the shape.

Robbyg, here is a smaller version with higher resolution. Same equation, no need to create array: t||(h=X=Y=0);for(i=950;i--;) X=950+(S(1*Y)-C(2*h))*440, Y=550+(S(3*h)-C(4*Y))*230, h=X,x.fillRect(X,Y,1,1)

A three-way adversarial deep neural network learning to draw a cat.

this is clever af
u/BirdsTweetCodersDweet

How is it a neural network? You're just drawing random squares on a cat emoji :P
u/pythech

whoosh
u/magna

Yeah, sorry, it was a bad joke. Just transferring random rectangles from an off-screen canvas. The only catch is the use of valueOf to cut down on the function call ()s.
