So I'm obviously Magnetic Pixel Kit ($31) lets you create a pixelated picture anywhere you can stick a magnet. Coming with 1,400 square magnets, you can stick Superman on your fridge or Iron Man on your file cabinet. It's all up to you.
Although it doesn't come with patterns, the kit does give you some tips on how to make these creations a little easier, like printing out a pixelated pic from your computer to go by. Overwhelming? Probably. Fun? Definitely.
