    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.

Golfed and slightly cleaned at https://www.dwitter.net/d/5543. Have fun with the extra characters!
u/Bugsy

(cleaned is referring to some slight blockiness on the right side of the animation, not the code. My code is much uglier :P)

Neat! TIL Javascript accepts python notation for exponents.

One of the most impressive images I`ve ever seen! Please create more like this. #neural #fractal

Thanks rodrigo :) I will certainly try, although one does not create these things, but mines them from the computational universe :D I look forward to finding more

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.
u/iverjo

Sigmoid activation function used in Artificial Neural Networks. Animation shows changes of neural weights plus a random bias.

u/pavel

I often use sigmoids for movement. The ease-out / ease-in looks great. I used 1/(1+1e9**(.5-t%1)) in d/11146 for the 'jumps'.
