Finnish software developer Jerry Jalava, in an unfortunate motorcycle accident lost a digit of his left ring (leech) finger. The prosthetic that took its place went on to become his claim to fame: it packs a USB flash drive. What looks like a good attempt at looking like a real finger, can be peeled of at its nail to reveal a USB connector. Once separated, the finger can be connected to a computer like any other USB flash drive.

Jalava modified a traditional prosthetic to pack a tiny 2 GB drive. "When I'm using the USB, I just leave my finger inside the slot and pick it up after I'm ready" says Jalava. The developer already has plans for the next version of his 'smart digit', which will have more storage, and an RFID tag. 'I'm planning to use anther prosthetic as a shell for the next version, which will have removable fingertip and an RFID tag,' he added.
