Aleandre Farto's explosive etching technique involves precision detonation of plaster and brick to make enormous, smoky murals. This video, with music by Orelha Negra, demonstrates the technique.
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.
