This is the best I could manage in 140 character. I had a this but could not shrink it: c.width|=0 for(i=9;i--;)for(j=9;j--;)[0,2,4].map(d=>x.fillRect(0,0,2,2,x.fillStyle=R(d*99),a=[20,-9,0,h=99+30*S(i+j+t),-20,-9],a.splice(d,2),x.setTransform(...a,(24+i-j)*40,(39-i-j)*18-h)))

Correction: c.width|=0;for(i=9;i--;)for(j=9;j--;)[0,2,4].map(d=>x.fillRect(0,0,2,2,x.fillStyle=R(d*99),a=[20,-9,0,h=99+30*S(i+j+t),-20,-9],a.splice(d,2),x.setTransform(...a,(24+i-j)*40,(39-i-j)*18-h)))
