This is a Starry Night Lego Stained Glass Window, created by Smock Man. Based on the famous painting by Vincent van Gogh. The Stained Glass effect is achieved by sandwiching a bunch of transparent pieces between two layers of clear panels. There is a one stud gap between the clear panels to work with. The impressionistic style of the painting lends itself well to be recreated in all sorts of different mediums. This creation can be a little fragile. Most of the pieces are not connected to anything. A good shake would probably move stuff around. The city part of the build is the only part (besides the frame) that is not transparent. This make it feel more solid than any other part of the scene. Everything else is pretty much all transparent Lego cheese slopes. With a few 1×1 round bricks representing stars. The main feature of this build is how it glows in different lighting. It is ironic that Starry Night would look best during the sunny day.
