Looking for a way to show your pops that you care and that you think he’s a big ol’ tech geek at the same time? Stop over at Fractalspin.com and check out its list of Father’s Day gifts. Featured are a number of accessories including duct-tape wallets, unique digital watches, a solar-powered messenger bag, keychains, tie tacks and cufflinks like the ones pictured above.
Made from two matching black microcontrollers the cufflinks are as the site says “classy and subtly nerdy at the same time.” They’ll only set you back $45, too. Not that you should put a price on how much you love your dad or anything.
