So why would I be covering ties on a tshirt review site? Well, as hard as it might be to believe, a well coiffed geek can’t wear tees all the time. And while we can’t always wear our favorite apparel there’s no reason we can’t geek up even the most formal attire.

First up is Computer Gear’s Engineering Graph Silk Tie (found via Fashionably Geek). It’ll cost $30 for the luxury of graphing an exponential equation on what is otherwise only useful as a napkin substitute.

Second up, in time for its 30th anniversary, is the ‘Space Intruders’ tie from Amazon.com (I’m guessing its ‘Space Intruders’ instead of ‘Space Invaders’ because of some kind of licensing [or lack thereof] nonsense). To get this game on your wallet will suffer a $24.95 setback.
