I probably spent more time trying to figure out the layout of this room than I did actually building it. I started out building the computer consoles. If I could not get the look right on these the room would not work. I started with some scrap wood and after some trial and error I ended up with computers that worked. I then designed the computer face decals and printed them on card stock and attached them to the consoles.
The chairs were a bit of a challenge because I wanted them to be movie accurate. I did the research and then racked my brain as to how I would make them happen. I used wooden paint stirs for the vertical and horizontal parts. I then added the contoured side, which were made from thin cardboard and glued to the horizontal and vertical pieces. The base of the chairs were made from those staples that close heavy duty cardboard boxes, I then added charm bracelet pieces to the sides and back and then gave it all a paint job.
Now that I had all my major pieces ready I made a wooden box for the frame. I cut the grid pattern in the back side of the room for the "artificial light" that the back half of the room has. The front end of the room has "natural light" from an apparent hole in the ceiling. I covered these holes with plexiglass and covered them with light blue tissue paper for the natural light and white tissue paper for the artificial light. I then strung out old christmas lights and glued them in place.
I used spray foam to texture the front half of the ceiling. Once that dried I gave it a coat of white paint and then sprinkled laundry detergent on the the wet paint to give it a snowy texture. I then screwed the computers in place. I then added all the cables, chairs, people, and droids.
I'm not sure what the function of the thing at the back of the room (by the stairs and doorway) but that little creation was probably my favorite part of building this one.
