    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 don't think you need "var" there. It works fine without it :)
u/New_Core

nice, and its 5 FPS faster with the "var" then without on my old machine.

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

magnificent
u/tomxor

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/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.
