I didn't use any plans, but the idea is very simple. Decide what size/dimensions you want and frame up a simple box. Measure the outside width of the surface and cut thin slats that width then stagger them. I use wood glue and brad nails. For the inside the lighting is entirely up to your imagination. I use copper wire led wrapped around wooden dowels. I have a bigger one here with better pictures that can give you an idea of how to make one.
