Well, I way overdid it, which seems to be my thing. The younger daughter wanted under the sea, so I did two walls in dark indigo, and an under the sea wall size poster on the two remaining walls. realistic plush fish and plastic jellyfish were hanging from thin mono-filament from the ceiling at various levels, and the room was lit (no windows) with a ripple effect theatre light. The only other light was an old ship’s lamp for a reading light. The room was too dark for much other than sleeping, but both kid’s rooms led into a common playroom. The Nostromo room also featured a smoke machine which was set to come on 20 seconds before the “self destruct” sound played. That was computer controlled, which could be set as a wake up alarm, or triggered manually from my laptop. I put way too much effort into it. We still have the Nostromo bridge chair and panel, as well as some of the signs I had printed and laminated.
