    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.

I wanted to make a tribute to https://twitter.com/BalintCsala/status/99216… but this is all I got so far
u/BalintCsala

Hah, thanks
u/joeytwiddle

I did write something which was technically more similar (points appear and disappear without moving) but it doesn't look any good at the moment

Spikey circle

u/BirdsTweetCodersDweet

if you add t=0 at the very start, and kkep typing +.1, you can step through and see all the cool patterns it makes along the way :D
u/BirdsTweetCodersDweet

Kinda reminds me of the old days of logo programming as well :P
u/trancor

That little turtle was great! Good looks! I added t=~(t*4)*.1; 4 is the slide show rate, .1 the steps.
u/BirdsTweetCodersDweet

Nice!

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!

Tried so hard and failed to get this working - h=(w=c.width=600)/2;!t&&(y=[],u=[]);for(i=99;i--;)k=y[i]||w/2,o=u[i]||h/2,n=C(i),m=S(~i),y.map((b,a)=>{d=b-k,v=u[a]-o,Math.sqrt(d*d+v*v)<50&&(n-=d/80+S(t),m-=v/80)}),x.fillRect((y[i]=(k+n+w)%w)/.9-9,(u[i]=(o+m+h)%h)/.8-9,6,6) Thanks u/MrM@_S for inspiration to look into obfuscation and cheating the char count ;)

u/trancor

Been seeing an error variable u undefined sometimes, just add a space after the last ), it will work then.
