LED Screen Acts as Virtual Astronomical Clock Replacement in Prague

Prague city council has installed a virtual replacement for the city’s Astronomical Clock landmark while the real thing undergoes renovations. On its website, Prague City Hall wrote: “A modern LED screen on the tower of Old Town Hall provides Prague residents and tourists with the experience of the astronomical clock. The LED screen is 5.56 x 3.84 meters and weighs about 1,000 kilograms”.

The screen is equipped with a sensor that automatically adjusts the image brightness according to the lighting conditions. Software was developed to replicate the movements of the various arms and wheels on the clock face. The video is accompanied by sound effects including a rooster and the tolling of bells. Sounds don’t play during nighttime hours.
