Justin built this rearrangeable Lego set with interior lighting. The base (shown below) holds the lighting element and creates a container for the urbanscaping inside. Five buildings and five landscape elements fit together in a variety of formats. What is really fun about this piece is that the rearrangeble elements are not tethered to a Lego base – instead they slide around inside of the base until the last element is dropped inside. This makes the process of figuring out how to configure everything really fluid. See more of the lighting set up on Justin’s Lego Flickr set here.
