Clever Kinetic Sculpture

Nice little kinetic ball sorting thing. The video (might take some time to load, it’s coming from China) has enough close up shots that is would not be that tough to duplicate this. I need to find a good supply of that brass wire he uses, looks like it’s brazing rod so it shouldn’t be too hard to locate some. I see a trip to Harbor Freight in my future!
