Clockus is a simple but beautiful clock application, which uses unique algorhytm to draw LED-style digits. Each of them is formed by 12 arrows situated in 6 points. These arrows are rotating to display numbers when seconds, minutes or hours change.
You can choose between themes (currently two, but more to come with updates) or change upper mask opacity (it hides those parts of sticks you don't need). Upcoming update will contain more themes for you to choose.
