    It's been decades since I have traveled through Boston Logan. They used to have a marvelous gravity well kinetic sculpture there. I almost missed a flight wanting to watch just one more pass.

    Reminds me of the "gravatram" at the Oregon Museum of Science and Industry (OMSI) in Portland. https://www.reddit.com/r/RollingBall...msi_gravatram/

    The beautifully made wooden gravity well sculpture is $5200 with a waiting list. I wonder how many hours of labor goes into making it.
    He makes other versions priced up to $8000, all with waiting lists.

    I want to know how many balls can be "in play" at one time? With no extra balls waiting at the start. When the last ball, leaves the start, the next ball returns so it is picked up the next time that wheel comes around!!!
