We realize this isn't for everyone, but if you are a fan of 8-bit Mega Man art, then Etsy has a shop for you. Eight Bit Robot is a new shop on Etsy, an online marketplace for homemade goods, which features perler-based sprite art of different characters from Mega Man, as well as Super Mario Bros. and Dr. Who. In addition to Mega Man, Dr. Light, Roll, and Rush, you can also get sets of Robot Masters from the first three games, Doc Robot, and even Mega Man in his Rush Adapter Suits.
Better still, you can get magnets added to them for no extra charge, meaning you can put together some neat battle scenes on your fridge (or another magnetic surface). And, in some cases, shop maintainer Luke Barton is even willing to change the colors to match palette-swapped sprites.
