Art school student Freddie Yauner’s CO2-powered Highest Popping Toaster in the World concept is great and all (it’s even supposedly Guinness World Record-certified), but a clock that aims to tell time to one millionth of a second is what it takes to turn our geeky, schedule-obsessed hearts to mush. Since no display can refresh a million times a second (and no eye can comprehend that kind of data), Yauner’s concept lets you peer into the moment by hitting pause. Just note that by the time you let go the clock will have already advanced by another several million microseconds, prompting an almost Heisenbergian cycle of observation in its owner.
