Ry4an sez, "Today's maker project was a pair of bedside lamps that switch one another. The effect is really jarring because the switches are so near the bulbs they'd normally control." I love this -- it's just annoying enough that you can imagine it appearing unintentionally in, say, a hotel room (the most notorious source of terrible lighting controls in the developed world), and yet perversely pleasing.
Crossed bedside lamps turn each other off and on
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.
