This an AR app that lets you place a wooden toy train set on flat vertical surfaces.
I wanted to fulfill a loooong forgotten childhood aspiration. When I was younger I thought that having a train set on a verticle surface would be cool. Alas, 5 year old me did not have enough duct tape and glue to make it happen. I figured I could get back to it sometime down the line when I had more experience in making toy train sets.
Unfortunately, in the present-day, I don't have access to a wooden train set so I had to make a virtual train set, to-scale, complete with one of my favorite toy trains: The Polar Express.
