Mention was made here of UHU2 paper model of the Discovery spaceship from the movie "2001: A Space Odyssey". I decided to find more information on UHU2. It turns out it is not a company, but a person in Japan. Evidently he creates and builds paper models of subjects in movies.
These are amazing. Would you believe the Lunar Module "Aquarius" from the movie "Apollo 13" with an interior? How about the submarine "Atragon" (known as Gotengo to the Japanese) with an interior?
He makes them available for download for a time. The two I mentioned are still available but others (Discovery, Viper, X-Wing, etc...) are no longer there. Check it out!
