I just ordered one of Dr Roberts's magnificent and functional steampunk lamps -- I wanted to make sure I got my order in before I blogged it and he sold out, because goddamn these things are fantabulously wondrous and made of purest awesomesauce. Dr Glenn Roberts is a horticulturalist at the University of Guelph, but if he ever wants to quit his day job, I think he's got a fine second career here.
Update: All sold out! Here's what you missed
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.
