German artists Dialog05 have put together a range of conceptual USB devices. These are pieces of “art” rather than actual working USB gadgets but pretty cool none the less.

My favourite has got to be the USB Bra, with the phrase “Unplug and play” being aptly appropriate :). They also have a few ideas which could work and be marketable in the “real” world, like the USB watch and USB padlock (a means of securing your data).

You can see and laugh at the full collection on the Dialog05 site (found via Digg).
