This is a custom made Luke Skywalker (circa Empire Strikes Back) USB drive. I assume it's painted modeling clay, but honestly it could be made out of unicorn tears for all I know. What an amazing job the artist did though -- such an expressive face. It's like you can hear him screaming, "WHY'D SHE HAVE TO BE MY SISTER!?!"
Hit the jump for several more shots of the expressiveness.
Thanks to Julian, who would also give an arm to make out with Leia.
