Kotaku has a lovely picture of the LucasArts cabinet being displayed at Comic-Con. Possibly holding a copy of every LucasArts / LucasFilm Games game ever made.
I guess if you haven't really got anything new to show at a nerd convention, old (albiet lovely) boxes will probably do the trick. At the least it shows LucasArts know their old IP actually exists. Here's that link again.
