My wife already got me the Tron Lightcycle hoodie for my birthday this year, but if I needed another hoodie this one would be high on my list. The “Traditional Greeting” hoodie is such a simple-yet-brilliant idea it’s surprising nobody’s done it before. The big hand printed on the front is aligned so that unzipping it halfway changes it from our Earthling traditional greeting (a wave) to the Vulcan traditional greeting. It’s now available on Threadless for $40.
Thanks to Julia S. for the tip!
