    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.

now we sit and wait for it to one day turn back into a circle lol
u/KilledByAPixel

its gonna be a long wait!
u/katkip

I think it is 49777670.4258 seconds with 60 FPS
u/katkip

This calculus took me a lot
u/KilledByAPixel

t=60*49777670.4258; Nope.
u/katkip

Oh.
u/katkip

It never gets back to circle because it is getting unsymmetrical
u/KilledByAPixel

I think eventually t will wrap around and become 0 again.

Super Tiny Fractal Part 2

u/joeytwiddle

Very nice #tiny
u/username

it is not a fractal though
u/KilledByAPixel

It is though... Also interesting if you change the ^ to a | or & it becomes an ordinary sierpinski triangle (also a fractal).
u/username

I agree with the Sierpinski triangle, but the other one is not a fractal on my screen.
