The use of projection technology is gaining traction. Check out a media company’s display, projected onto the medieval Prague Astronomical Clock Tower, celebrating its 600 year anniversary. The videos show it being built, torn down, rebuilt, and peeled away to show its internal mechanisms, 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. An impressive sight to behold!
