Here are a couple of MOC's based on the tv shows Stargate SG-1 and Stargate Atlantis.

For those of you not familiar with the shows, the stargate is an ancient device capable of connecting Earth with other planets via temporary wormholes. The Promethues is the first image in the gallery, and was built in the sixth season of Stargate SG-1 by the US Airforce. Based on alien technology, it was the first Earth built space craft with a hyperdrive. Colonel Jack O'Neil, played by Richard Dean Anderson suggested that it be called the Enterprise, an idea that was nixed almost immediately. The Prometheus was the prototype for Earth's interplanetary fleet, and was destroyed in battle during the 9th season of Stargate SG-1. I spent much time downloading pictures of the Prometheus for reference, and while I wasn't entirely happy with how boxy it looked, I got a lot of compliments on it when I entered in the Model show at the Toronto Trek (now known as Polaris) sci-fi convention a few years back.
The rest of the pictures in the gallery are my rendition of the City of Atlantis, as featured in the tv show Stargate Atlantis. A spin-off of Stargate SG1, the Ancient city of Atlantis was discovered not on Earth, but on a planet millions of light years away in the Pegasus galaxy. Atlantis is actually a giant space ship, floating on the surface of watery planet similar to earth. I had a very hard time getting this to look correct, since the city looks like a giant snowflake, and has very few right angles on it. (Why do alien cultures hate the right angle? Why?)
I still have the Prometheus on my shelf, but I had to disassemble Atlantis, it was almost 3 feet wide, and took up my entire floor. I entered in the model show at Polaris 2 years ago.
