    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.

sadly had to use compression, the actual code is quite elegant =P

u/KilledByAPixel

nice work, it is possible to fit! here's one https://www.dwitter.net/d/6152

This is it's quite elegant code: f=($,e,l)=>{if(l>1){let _=l/3;f($,e,_),f($+_,e,_),f($+2*_,e,_),f($,e+_,_),f($+2*_,e+_,_),f($,e+2*_,_),f($+_,e+2*_,_),f($+2*_,e+2*_,_)}else x.fillRect($,e,1,1)},t<=0&&f(0,0,1080);

#default reflected in rippling #water (night, redux)

u/joeytwiddle

This is more efficient than fillRect() but it's too long! c.width|=c.style.filter='invert(100%)' (This way, we also need to change clearRect into fillRect)
u/magna

c.style.filter='invert(' suffices since browsers are notoriously forgiving
