Bored with the old minute and hour hands? Looking for a challenge when it comes to the simple task of telling the time? Well, good luck figuring the hour of the day with Designer Branislav Sipka's Aqua Clock.


The Aqua Clock has a "mechanism" (whatever that means) within it that allows water to fill up and empty out, and the markings on its frame are presumably to help you work out the time. But a closer look shows no way to tell morning from night, or to quantify the the minute of the day exactly. Puzzling. [Yanko Design]
