Telmo Pieper is a Dutch digital artist who, at some point, got his hands on some of his old drawings from when he was a 4-year-old child. Because, apparently, not all mothers leave all of their kids' stuff out on the front curb the weekend after they head off for college. That's probably also why not everyone needs to spend $300 a week on therapy bills. But, I digress.

Anyway, upon finding his old art works, Pieper decided to re-create them in the computer. And, man, did they come out looking cool! See for yourself:
