    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.

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
