After about 18 years up on the wall this marble track is coming down so we can do some improvements around the house, including this bedroom. It’s still one of my favorite projects.

This marble track all the way around my son’s room. Two gear motor contraptions lift the 1” marbles on opposite sides of the room to keep everything moving on the wood tracks made with pieces of 1/8”and 1/4” thick baltic birch plywood. Enjoy!
