Golfed to fit

u/marquisdegeek

Storing the gfx data like that is sweet! So nice to see if without obfuscation!
u/BriSeven

if you deduplicate the symmetry, rotate it (so that it is 8 rows of 16 pixels), and prune out the two rows that then are just zeros... we can shave the graphics data all the way down to 鰜鹞廾皶㜷彟
u/BriSeven

which would be worth it if you can find a way to undo all that which isn't more code than the characters we save
