    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.

Protein folding in 117 characters (extra bonus: view fullscreen to see ribosome α-helix spiral filaments)

So organic I love it!
u/rep_movsd

Brilliant
u/danny@hille.dk

The product is pretty, but the code is, while not easy to read, perhaps the most aesthetically pleasing code snippet, I have ever seen!
u/smtsjhr

is it a sufficient condition for the appearance of α-helix spiral filaments to just use 'α' character in the code?
u/DataMeta

this is amazing!! #organic

u/rodrigo.siqueira

Sure Smtsjhr, I think you also noticed that there is a β value responsible for the Beta-Helix (secondary structures in proteins, forming helical patterns of β-strands). I've just created a remix, changing "α and β" parameters to "lighted circles and donuts", as you can see in the remix link.

You can save 7 chars by doing f=i*t,X=f*f%9,Y=X*f%5 in these instead of Math.random. It seems random enough.

Oh cool, thank you!! I like the way it changes the animation at the beginning too.
