If you've got some spare Lego
bricks, a rather tiny USB flash drive (might we recommend a Lexar USB FlashCard
?), a bit o' spare time, and no discernible fears for the safety and well being of your digits and extremities when applying tools to rather small, hard plastics, then we'd like to point you to Stickman's Lego flash drive how-to. Novelty, yes; but why is that a bad thing?
