I was in Prague last month with my girlfriend. We spent most of our time just wandering aimlessly. At one point, we saw what looked exactly like a giant metronome swaying back and forth on the top of a hill on the other side of the river (the side where the castle is).
Does anyone know what this is? We went up to the top of the hill (which is an improvised skate park), and the metronome didn’t appear to be connected to anything but a wire. Therefore, it seemed that the electricity from the wire was what made it sway, not the wind or anything like that. I could think of how the metronome would be generating anything.
Does anyone have the slightest idea what I’m talking about?
