That brings an interesting new restriction to mind.
You have 171 white, black, light grey, and dark dark grey pixels, and 170 grey and dark grey pixels. You have a 32 by 32 canvas. Make something awesome, GO.
Hahaha, that'd be hard. Very hard. And tedious counting of pixels of certain colours. But I'd like to see someone try, I would. And my math must be off, because I somehow managed to calculate 1024 pixels inside a single 32 by 32 space. That's craaaaa-zee.
I go bed now midnight ramble.
