Hubblesite.org is offering three awesome, free how-tos to recreate model Hubble telescopes. There's excellent instructions and lots of free printable parts and decals "These models aren’t working telescopes – you can’t peer at the sky with them. But they can give you an up-close look at the telescope’s structure and a challenging project to engage your model-making skills."
The first is the easiest to make, and uses a short length PVC pipe to support the main structure. The other two save you a trip to the hardware store, and are pure paper, created without special materials (though you'll need a few supplies from your stash).
StarTrek fan Tony Alleyne used his love of arts & crafts and science fiction to turn his 500 square foot apartment into a replica of the Enterprise's transporter room. Two years after he completed his StarTrek makeover, Tony started his own design company, 24th Century Design, hoping to help others bring their sci-fi fantasies to life. Reports suggest that Tony paid about 100K British pounds outfitting his pad with such things as voice-activated lighting. (I hope you have to say 'computer' first.)
