One of AmputeeOT's followers challenged her to make a prosthetic leg out of Lego. In terms of practicality, it's a bit of a chocolate teapot. But she sure has fun with it, and that's what matters. She notes "Please don't do this yourself, I don't want you to fall and get hurt!"
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
