Mark Stafford's "Steam-Dinos" is a Lego fantasy with its own backstory:
“A spiffing way to go to war I decided as we powered through the veldt. Mr. Roberson’s patented Triterrortops steam powered terrible lizard replica was performing above the expectations it has been set by His Majesties Royal Calvalry Corp. My report to the Generals will be that the vehicle has proved more then adequate to combat the clone-vat monstrosities of the Zimbab bio-shamens.(sic)
Also: it really walks!
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.
