nice find geb, check 2923 datameta, altho xem and others have done smaller ;)

rotating square

u/Ghoust

does anyone know a better way of doing this?
u/danny@hille.dk

I'm not sure it's better, but this another way: c.width+=0; x.translate(960,540); x.rotate(t); x.fillRect(-250,-250,500,500)
u/KilledByAPixel

for(c.width|=i=4;i--;x.fill())x.arc(960,540,500,a=i*11+t,a)
u/rodrigo.siqueira

I like this 3D rotation: x.fillRect(700,300,400,400) ; c.style="transform:rotate3d(1,5,2,"+t*2+"rad)"
