This weekend’s project was adding another shelf for my open top staging. These are floating shelves with a 1 1/2″ trim strip on top to keep the cars from rolling off. Steve Jobs big thing was his obsession with ergonomics and the user experience. A lot of this is subtle. I find that if I need to rummage through boxes in storage to find a car, I’m not likely to do it. With the shelves you can quickly cycle them on and off the layout.
