Crown with gemstones

Show more comments…
u/joeytwiddle

Gemstones for only 1 byte? That's a bargain! Although I notice the background now turns yellow for half of the rotation. What a curious bug! I haven't investigated the code.
u/ximavus

Gemstones for 1 byte is crazy
u/cantelope

jewel encrusted?
u/alexsav

Yeah the background is set by a fillRect(0,0,n=m=15e3,m) call in the beginning. The fillStyle will be whatever fillStyle was set to by the last fillStyle call in the for loop "R(r=b>0?n*m:k,r+r*(C(6*s)-C(n/133)))". When n=0 for the last one, this will alternate between black and dark yellow depending on b>0, which is related to the rotation of the crown.
u/ximavus

its packed jewels
