Jesse Herbert of oopsmark was making leather wine carriers you could sling from a bicycle when an idea struck him -- he could use the leftover bits of leather to make accessories. But not just any accessories -- smart accessories. Somewhere between steampunk and cyberpunk, came a set of wrist cuffs with USB keys stowed on them.

At Macworld|iWorld 2013 Jesse showed us his work and told us his story.
