Each wheel is marked with a black nut to highlight a position that could be tracked over time. Along the arc, 100 lines mark the divisions of each passing year. When the clock finally reaches the end of a 100 year cycle, the arc falls off its track onto the floor.
I recently had to write a self-reflective essay for the end of my degree. They asked me what inspired me and I said that pretty much the only thing was humanity's ceaseless ability to produce wasteful, expensive, totally pointless and useless crap born of jealousy, greed and the simple desire to do something, anything that just makes your head spin and your jaw drag along the ground. The kind of thing that when you see it you just have to phone everyone to tell them about it in case it's existence was just something you dreamt about. This thing is staggering, just incredible.
Many, many thanks to James Allen for bringing it to my attention.
