Remember the kid you picked on back in high school who was winning math Olympiads and what not? You should probably give him a call and apologize this holiday season. In fact, a gift is more appropriate. So why not get him these totally radical circuitboard coasters? Made from REAL circuitboard and not painted on, these coasters are the epitome of geekdom. Now I know this is not the first time you've seen a circuit board used as a coaster. But all hues of the PCBoard rainbow are represented here—amber, green, blue, and others. You can net a set of six coasters for only $20. You'll still get picked on if you use them, but at least you won't have those ugly water rings on your wooden tables.
