Need a stocking stuffer for that diehard Firefly fan? How about getting him or her an 8 G capacity flash drive in the form of a three inch diecast metal replica of the Serenity? It has a loop for your keychain, a push button to eject the drive, and the engines even light up. In the above photo, it can be seen docking at a laptop having narrowly escaped the Alliance and Reavers to offload or collect goods. It’s useful, rugged, shows you’re a fan of the show, and it’s available for $29.99 from ThinkGeek.
