Flikr is a social image-sharing application: it's a mechanism for creating ad-hoc chats, using a drag-and-drop GUI interface that lives inside your browser, and share images from peer-to-peer and within conversational groups.
I've beta-tested this at various points and at each time I've been struck by Ludicorp's amazing combination of utilitarian, usable interface aesthetic and genuinely witty whimsy. As Ben Ceivgny, a developer on the project, said:
We collect images with cameraphones and so forth, but we have no good mechanism for advancing them out into the world. Here's a mechanism for batching them into a locked-and-loaded tool for firing them into the world.Link
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.
