    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.

Rotating Lorenz Attractor

u/jwc

Deleted my previous attempt and replaced it with this instead because I found an obvious savings that allowed me to improve rect size. If you can save 5 chars, you can replace s*S(t) with (s-28)*S(t) to center the rotation. Alternatively, if you can save one char, you can remove b, make the last two args of fillRect …,4*i/t,4), and use the previous centering method with a small concession to the rect shape.
u/magna

Done! d/21062
u/magna

The key was replacing (q*o-2*s)/50 with q*o/50-s/25

Nice!!

I know it’s not that sophisticated, but it’s my first attempt at a dweet. I’m learning a lot looking at all the amazing work here.

u/jwc

I wanted to do something like d=6+S(p)*(1+b%2), but I couldn’t figure out how to make it fit.
u/pavel

arc?
u/jwc

Hah, of course! I was originally planning on trying an effect that squeezed one axis differently than the other and gave up on that, but didn’t think to replace ellipse with something else afterward. arc makes it perfectly fit in 140 with the above revision to d. Thanks :)
u/andrea270872

Nice. I get a vibe like "beam me up!" :)
u/jwc

This looks a lot better, but probably not different enough to be worthy of a remix :)with(x)for(c.width|=b=190;p=t+b/.6,r=64-64*S(p),b--;fill(arc(960-180*(1+b%2*2)*C(p),6*b,6+2*S(p)*(1+b%2),0,7)))beginPath(fillStyle=R(r,r,r))

how does this work!?
u/KilledByAPixel

it is a cellular automata, each frame it tires to move the snow down and left or right randomly if the target cell is empty
u/Odog8

oh wow
u/tomxor

Wow nice! it's great how an effect can take on new meaning when finding a different way to frame it.
