Mechanical nocturno at NT Museum
Sonic memories on the night tours in The National Technical Museum in Prague. I worked there in the beginning of 80ies as a night watchman. Part of the duty was to walk every 3 hours with a flashlight and turn the key in a special clocks around the building starting from the basement and going to the upper floors. Soundwise the most beautiful was probably the exposition about Time:whole room ticked and clicked. It was like a mechanical dream. Most mysterious was the last floor where STB had its secret offices.
