I just stumbled across this on Twitter and am utterly fascinated. Simply Tweet Tegu (@Tegu), a brand of magnetic building blocks, what you'd like to see built and their artist creates a mini version of it right before your eyes on their website. If he's not building when you pop over to their site, don't worry - there's an archive of his past creations. I just wasted a chunk of my afternoon watching him build a mushroom and olive pizza, a convertible, Hedwig from Harry Potter and a school bus.
