When I was much younger, I loved building plastic models. Most of them were cars but I also built planes, rockets, and even a ship or two. But what I did cannot be compared to those master modelers that build stuff for movies or TV.
One of those masters is Martin Bowers. He has all kinds of scratch built models including ones from Space 1999 here.
This link here is to a five-foot long model of the Star Trek Enterprise 1401-D. It includes a full lighting package using neon lights!
It is too bad that with the coming of computer generated images, the need for miniature models is on the decline. That being said, feel free to spend some time taking a look at some really amazing work.
