My little nephew Jaxon (2.5 years) is crazy for Eric Herman's "Elephant Song" and the accompanying video on YouTube -- and now my daughter (1.5 years) has caught the bug. It's some funny stuff, provided your sense of humor is still at toddler level (as mine apparently is!).
The Elephant Song - Cool Tunes for Kids by Eric Herman (Thanks, Jaxon!)

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.
