The Flashbag is a USB flash drive that will inflate as it fills up with data. Similar to how I inflate when filled up with donuts and beer. Now you may be asking why a gadget like this would be useful. Well, it really isn't, but it is definitely cool and an innovative USB flash drive design, which is pretty rare nowadays. The Flashbag is only a concept right now but the designer, Dima Komissarov, has a patent pending on this device, so hopefully a company will pick it up soon.
