Wish you could instill a bit more stress, anxiety, fear, and complete and utter boredom into your life at home or the office? Then simply hang up one of these retro cool Double-Sided School Clocks. These old school, literally, double-sided clocks from National Time are vintage timepieces salvaged from an old high school in Iowa that have been rewired to be fully functional. While designed for walls, the clock face can also be re-orientated for hanging it from the ceiling as well. Most interesting of all, if you stare at one long enough, time will begin to slow down to an excruciating pace and you may experience cringeworthy high school flashbacks.
