    Full speed 138: p=i=>99*[0,0,3-i,1,6-i,2,i-5,i-7][~~i] for(c.width|=i=8,x.rotate(7);i--;m+7&7&&x.fillRect(p(m?i:T=t*5%8)+700,p(m?6-i&7:8-T),90,90))m=~~T-i

    Nice! There is some flicker but you saved enough bytes to fix p=i=>99*[0,0,3-i,1,6-i,2,i-5,i-7][~~i];for(c.width|=i=8,x.rotate(7),T=8*t%8;i--;m+7&7&&x.fillRect(p(m?i:T)+450,p(m?6-i&7:8-T),90,90))m=~~T-i

    This was fun. I also tried two totally different implementations but it seems your approach is the best.
  • u/katkip
    Haha that's fun
