The Astronomical Clock Tower in Prague’s Old Town Square just celebrated its 600th Anniversary. Part of the celebration included a visual mapping ceremony on the Tower’s facade that is, simply put, mind-blowing . We’ve covered some amazing video mapping here before and are big fans of the art, but this time artist Macula took it to another level. Pealing the bricks off the Clock Tower’s face, one sees the gears of the clock in motion. Then the visuals take you through a brief history of what the Tower witnessed in its native Czech Republic.
