    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.

It uses pretty much the same formula as the previous dweet, but just prettier

#raytracing z = sin(sqrt(x*x + y*y) - t)

u/pavel

Also a pretty generic ray tracing 'engine.' Change f to trace other things.
u/pavel

Style remix, no idea how the code I'm remixing works yet. It does not look to do ray tracing so its clearly better.
u/primo

The original uses z + ∂/∂y z for saturation, which looks about right tilted at or near ~26.5°.

for(c.width&=i=10368;i--;x.fillRect(i&127,i>>7,f(.7),1))f=n=>(z=5-i/3e3-3*n)>S(Math.hypot(i/64%2-1,i/5e3-n)*9-6*t)?f(n+.03):--z*.4 is a better one, no weird view prism.

#mandelbrot spaceship

u/rodrigo.siqueira

Instead of r*r+j*j<4 you can use just r<4 , that's 6 characters less. In this low resolution there's no visible difference.
