Facebooking and smartypantyphones be damned, I'm going back good old too-cool-for-school school. All the way back to the 80s, with stupid jackets, antiquated business cards, and this anodised aluminium NES Controller Business Card Holder.
$US31 will get you the pretty case with fake buttons, and two compartments: One for your business cards, the other one for the cards you collect. Or, alternatively, one for rolling paper, and the other one for papers with a lot of small funny pictures on them. See, I'm full of good ideas. [Geek Stuff 4 U via Akihabara News]
