    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.

Now I'm not into that modern emoji art stuff, all them young kids do nowadays, but if so, i vould have gone for an orange-peal joke for(W=c.width=203,i=700;j=i%2,i--;){a=4*(i%50-j);b=.18*(i-i%50);r=100*T(t)*Math.exp(-10*((a+b)/W+S(t)));x.fillText('🍊',r+a,r+b)}

u/sanny@hille.dk ^^ i appreciate how the orange emojis collectively create a porous texture faithful to true orange-peel!

** i meant u/danny@hille.dk i think your code is deserving of its own proper remixed post!
