    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.

So organic I love it!

Brilliant

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?

this is amazing!! #organic

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.
