Maybe next time I’ll pull out a business card in an attempt to keep them organized.

There are a few more entries in the “Business Card Hacks” thread, including a handy iPhone/iPod Touch holder for watching videos. In addition, a Google search for “business card origami” yields plenty of interesting results, though I couldn’t find any quite as handy as the earphone wrapper.
