Ever think you can use your huge amount of Foursquare check-ins for anything other than those achievements on Foursquare? Rachel Binx and Sha Hwang have their own neato thing to do with your data:  Make custom, geometrically designed jewelry based on where you’ve been.

How’s it work?  Go onto their website, meshu, and you can either create your own design, or log into Foursquare and let it connect the dots.  It kind of makes me regret not checking in on any of my vacations, to have a cooler all-cities design.

They are crafted via 3d printing, or laser cutting.  So for between $75 and $150, you can claim mayorship in the “odd taste” category.
