    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.

Langton's ant! Initial settings (c.width=198,X=99,Y=56,D=0) can be changed. D%4 = direction where 0,1,2,3 correspond to down,right,up,left.

Faster version: speed=40;g=(j)=>(1-(D&2))*(j^D&1);while(speed-->0)t?(i=x.getImageData(X+=g(0),Y+=g(1),1,1),D+=(i.data[3]^=255)?1:3,x.putImageData(i,X,Y)):(c.width=198,X=99,Y=56,D=0)

I used Zero-fill Right Bit Shifting to limit the color to 32 bits. This will only work in modern browsers with support for the new hexadecimal RGBA notation: #RRGGBBAA

u/lionleaf

Still haven't seen this in a browser where it works. Chrome on MacOS and Firefox on Ubuntu so far.
u/iverjo

Works in FF for me. Also, Chrome has a blog post about this and says it should work in Chrome 52. Yet it doesn't work in my Chrome 55 on Windows
u/iverjo

Also doesn't work in Edge
u/iverjo

I guess CSS4 isn't ready for prime time yet :P
