In an age of pen drives and CDs, there's not a lot you can do with a 3½-inch floppy besides turn it into something else altogether - and as re-use for computer bits goes, this greetings card idea is not a bad one. I like the way that the finished result created is an image of another 'obsolete' piece of technology: a vinyl turntable. The 'record' also really moves, which makes the project all the more satisfying. Full instructions on how to do it are here.
I wonder who'd appreciate a card like this though? Possibly someone who's a bit of a throwback! [Via Craftershock]
