    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.

Pseudo falling physics

u/iverjo

Deserves more kudos :D
u/BirdsTweetCodersDweet

changing the last part to ... **2*25makes it more realistic, with more gravity and even a little bounce at the end... Also, removing the W variable saves you a byte :P
u/jylikangas

Actually you could use T in place of W and use it in place of every 20 to save 3 bytes. :)

Abstract smoke! Nice! Could look nice if it left a trail?
u/joeytwiddle

Tried shadowBlur but very heavy. Trails look better anyway: x.fillStyle='#fff3',t?x.fillRect(0,0,999,800):c.width=999;x.beginPath();w=540,t?m=[w+S(t)*340,w]:p=[];p.push([[...m],5]),p.map((z,i)=>{k=z[0],k[0]+=S(i+t),k[1]-=z[1]+S(i*8),x.lineTo(...k),x.stroke()})
u/trancor

Oooo, I like that, great idea! I'll have to try incorporating that into a remix. Thanks joeytwiddle!

Looks good! To stop the jumpiness, replace -K/6.5 with -K/6.2

u/BalintCsala

You could use with(Math)
u/BalintCsala

And x**.5 instead of sqrt
u/BalintCsala

And simply x**5 instead of pow(x,5)
