Mark sez, "My amazing and beautiful wife arranged had an R2D2 cake made for my 40th birthday. It was made by Stacked Cakes which is located in a small country town 20 kilometres outside Canberra in Australia. The link is to their log where there are photos and video of it being made."
They also include downloadable templates for making your own R2D2 monstercake.
R2D2 Step By Step
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.
