Already have a small lego table but son is outgrowing it. Would love to do this on a bigger size table for him. Would be good for a kid's playroom. If you did velcro to attach it, you could switch out the base plates maybe.
Like this idea - Scan childrens art work and then print out in smaller size. Now make art gallery in hallways of your childrens art:). Awesome idea, even for my grown young adults to have all of the kept keepsakes of their artwork in one frame.
