The Prague Astronomical Clock or Prague Orloj (Czech: Pražský orloj [praʒskiː orloi]) is a medieval astronomical clock located in Prague, the capital of the Czech Republic. An astronomical clock is a clock with special mechanisms and dials to display astronomical information, such as the relative positions of the sun, moon, zodiacal constellations, and sometimes major planets. This clock was first installed in 1410, making it the third-oldest astronomical clock in the world and the only one still working. The clock mechanism itself is composed of three main components: the astronomical dial, representing the position of the Sun and Moon in the sky and displaying various astronomical details; "The Walk of the Apostles", a clockwork hourly show of figures of the Apostles and other moving sculptures—notably a figure of Death (represented by a skeleton) striking the time; and a calendar dial with medallions representing the months. In October 2010, the Clock's 600th anniversary was celebrated with a light show on the face of the clock tower. Two 2x Christie 18K HD projectors, each with a 1920x1080 resolution, were used to project several animated videos on the clock. The videos showed it being built, torn down, rebuilt, and peeled away to show its internal mechanisms and the famous animated figures, as well as various events in the clock's history. The video interacted with the tower's architecture, such as rain rolling off the arch, and showing the passage of time with moving shadows. The show was developed over the course of four months by the macula, Duber Studio, and Michel Kotek, and was presented by AV Media.
