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.
