Glashütte Trash Clock – A 30-minute pendulum clock made from trash
What happened
“Glashütte Trash Clock” is a fully functioning clockwork made from trash and other stuff that I found in Glashütte, Saxony. Since the mechanism just runs for about half an hour, it only displays seconds and minutes, striking a gong whenever the minute hand reaches the 12 o’clock position. As a little extra, the clock also triggers an external randomizer just before it runs out of energy.
