    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.

A little bit of Phyllotaxis. http://algorithmicbotany.org/papers/abop/abo…

btw, changing the angle a from 137.5 to 137.3 or 137.6 produce different, albeit nice, patterns.
u/Bendoman

Second best thing on here by far.
u/dubistdu

WOW
u/trupples

Also.. shouldn't it be 137.5 * pi / 180 ~~ 2.39982772149 as the trigonometric functions take in radians?
u/trupples

137.5 also kind of "isolates" the spirals after a short while while 2.4 does not
u/Pjaerr

Yeah, that'll be it actually. I still thought it looked decent!
u/DiamondDrake

I was just working on a Phyllotaxis dweet, though i was trying to use ellipse that just needs way too many characters
u/@no_identd

Although the point about radians is fully correct, I'd like to point out that the most accurate IEEE single float approximation of this angle in degrees is 137.50777 (which internally becomes 137.5077667236328125)

I had implemented so many more features, like a nice gradient while drawing, but had to scrap a lot to get it in 140 characters... :( DwitLonger please!

its all in the codegolf, you'll learn some shortening tricks by looking around here, t?x.lineWidth=3:x.t(960,540)
