Black Pi Wall Clock
OK sure we all check the time on our phones, but that doesn't mean this clock isn't awesome. If you are one of those people that still glances at wall clocks, if you love math, and if you are a grown-up person who can read the time without every number on a clock's face—this is the clock for you. At your house, it'll always be Pi time. $40. Etsy
