The Aqua Clock concept designed by Branislav Sipka shows an interesting new way to look at time. Inside the clock is a mechanism that moves water up and down in order to display the time of day. Unlike traditional clocks that are mounted flat against a wall, the Aqua Clock is designed to be installed on its side allowing you to view the time from both sides.
Of course telling the time with the Aqua Clock may be a bit more puzzling than traditional clocks but the markings on the side of the water may help decipher the time of day. In a simpler sense, the water level could just indicate the remaining time left in the day. Although you might not be able to get the exact time with this clock, it would definitely be an interesting piece of art to add to your home.
