I saw a brief mention of the ChonrArte Canna on Mocoloco but was so blown away by it, I felt it needed its own post. This gorgeous clock uses real liquid for its liquid display, which is made up of 12 tubes that slowly fill with colored water. It's meant to represent "flowing water as a symbol for time and its passing" and also "time as an endless river." It's about 47" tall and 28" wide if I'm doing my metric conversion correctly. It uses radio recpetion to sync the time and automatically changes from standard to daylight savings time.
