Any secret door wins me over instantly, but a secret door that reveals Han Solo frozen in carbonite? Wow. Just wow. And it only cost $150 to install.
Disguised as a bookcase holding the owner's Star Wars collectibles and knick-knacks, the shelving can be pushed to reveal a hidden home cinema. On the other side of that door lays the best part—Han Solo himself. Whatever this guy does for a living should be given up pronto, as I'd be willing to fling him a few dollars to build me a secret room. [Instructables via TechEblog]
