A nightmarish vision straight out of The Space Merchants: a gadget that purportedly vibrates train windows at the right frequency to beam advertisements straight into your head by means of bone-conduction, should you tire and rest your head against them.
All the references to this point to one video posted by someone with no other videos in her or his account, and there's not much other detail (Adweek attributes it to BBDO Dusseldorf). I'm betting hoax and/or grad project-cum-design fiction, but in this topsy-turvy world, anything is possible. The comments on the YouTube video are even more internetrage than usual, and may be the most interesting thing about it.
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.
