    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 think this might have been drawn on Dwitter before, but I can't find that dweet right now. I love the simple design!

Me too! It's minimalistic.

Glad to see this code is blocked by the <iframe sandbox="...">

u/joeytwiddle

But what is stopping it from running here? https://www.dwitter.net/e/9056
u/joeytwiddle

Oh easy answer: The embed page also uses the same <iframe> :-)
u/joeytwiddle

For some reason I thought the embed route returned a page without an iframe. Is there any route which does that?
u/joeytwiddle

Ahh here is the non-sandboxed URL: https://dweet.dwitter.net/id/9056?autoplay=1
u/joeytwiddle

Oops the URL I had meant to share was http://www.zombo.com

This is so cool! Also, in fullscreen it looks like the innermost part of the storm is slowly rotating clockwise #opticalillusion

Many of the start points exhibit patterns, e.g. t=98.99+t/2e2
u/vain

WTF? Amazing!
u/joeytwiddle

This was a happy accident. I was drawing a spiral, and thought "What if the arms rotate with i*i instead of i?" Of course, this makes the outer points spin faster, and distributes the points semi-randomly.
