The NixiModerne clock is a stunningly designed piece of German beauty. The casing is a streamline design made of clean metal onto which the glowing tubes are mounted. With each number illuminating into a fiery red, this is a clock with a difference. This monster, which weighs in at 25.5 pounds, contains some of the largest Nixie tubes ever made. Unfortunately that means that tubes are hard to find and extremely expensive. We can always dream, though.
