Any door can be a Star Trek door
One nifty aspect of "Star Trek" are the doors that slide open with a whisking sound. While most of us will forever use conventional swinging doors at home, one supergeek took matters into his own hands with the working air-powered Star Trek-style door.
Built by Instructables user uiproductions, the door gives me a nerdgasm. The Instructables Web site has complete DIY instructions (just hit "next step"), which will help you start your journey on the path to converting your living room to a starship bridge.
Imagine hearing the familiar whooshing sound of your own door opening at home with the press of a button. Unfortunately, the fellow uses conventional-style white doors, which is rather anti-climactic. If I attempted something like this I'd go all out with Tron-esque glowing accents and a motion sensor, but I suppose this will do for now.
