This is a sketch I made to help explain to my dad an older idea I had for the project. The idea was to use two flat magnets and cut a hole in the glasses so it'd be able to rotate like a hinge, but there was no realistic way to cut into the glasses to create the hole, so that idea got scrapped. It's very difficult to describe. I think the smallest picture at the bottom does the best job of sort of explaining it (surprisingly). Also, every single magnet that I could find in the house is on the sheet of paper. They're mostly just refrigerator magnets.
