We're all fairly familiar with conventional analog and digital chronographs, so the Aqua Clock by Branislav Sipka offers a new way to perceive and measure time.
This fluid fixture has a very minimalistic appearance, which is composed quite simply of a white circular frame and a double-glazed glass chamber that holds the water within. Faint notches along both sides of the window demarcate the approximate hour relative to the liquid's level, but the idea behind Aqua Clock by Branislav Sipka is to allow the observer to appreciate the concept of time in a different way.
Whether you're a "glass is half full" or a "glass is half empty" sort of person, your perception of time as you read it from this peculiar wall clock may be drastically different.
