Here’s a really cool DIY project for creating a USB Flash Drive that looks like a sawed off old cable. It’s the ultimate in “Shabby Geek” style gizmos. It just looks like you wouldn’t want to touch it for fear of zapping yourself but inside that old wire is a fully functioning (albeit small) USB flash drive. As far as DIY projects go, this one is not too difficult at all- no soddering required. Complete instructions to make your own available here.
