u/anotherkitten

this image always makes me feel like the c.style.background there
u/metamero

@anotherkitten you such cool and cute dwitter profile / person !! <3
u/metamero

the only difference from this and the other is the balls are a bit smaller (r=12): arc(r=p*99,s=q*99,12,0,7)
u/metamero

one can try different screens and also change the background to #888 or etc

play with x.fillStyle;-)

u/lowpoly

For example, x.fillStyle=Math.random()>0.5?'#000':'#fff'
u/lowpoly

or x.fillStyle=(~~(i/s/s)%2)^(~~(t*s)%2)?'#000':'#fff'
u/sigveseb

So intense colors!
