Caviar vending machines have been installed in three upscale malls in LA. In addition to $500/oz caviar, they also dispense blinis, mother of pearl spoons, and other caviar essentials. The vending machines (they're billed as "ATMs for caviar") can be found at Westfield Century City, Westfield Topanga, and the Burbank Towne Center. Apparently, these are old news in Russia, where they are favorites of oligarchs and their entourages.
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.
