The fun folks at Pixeljam have released a challenging new side-scroller called "Potatoman Seeks the Troof," in which you play a little spud in search of enlightenment, traversing a series of difficult terrains, trying to attain it. I've been playing it for a couple of days now, and I've found it good, addictive fun, with a nice balance between level-memorization and hand-eye coordination.
Potatoman Seeks the Troof: fun side-scroller
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.
