Most geeky lifestyles don't involve going to a lot of formal events, but there always going to be the occasional wedding or other fancy occasion when we need to put away the hip mounted cell phone and get dressed up. Still, you'll probably want to maintain some way to signal any fellow geeks at the event, so that you can hook up at the reception and discuss whether Chris Pine or William Shatner makes a better James T Kirk.

These Millennium Falcon cuff links from artist Lauren Swingle should do the trick. Hand made from polymer clay, you can buy them as is or have them customized by the artist as you wish. And at $22 a pair, they're affordable enough to get for a one time event.

Of course you could always make a bigger splash by rolling up in a geek approved vehicle.
