They're pretty cool, displaying a number of different scrolling data messages at the push of a button, and apparently cost just about $5 per card. The "slender" description means you'll have to be good at soldering surface-mount components, though. To me it's a cool project that will impress people, but kinda misses the point of business cards: easily disseminating your contact info. An LCD QR-code business card— now that's something I'd fancy. Head over to Instructables if you've got the LED maker-urge. [Instructables]
