As part of a basement renovation I got to make this really cool secret door inside a cedar closet. I designed the entire system from scratch and built it using standard materials from the hardware store and some parts I had laying around my shop. 

There are two videos next in the gallery; the first one shows a quick look inside the closet showing how it appears to be a standard cedar closet, and the second shows the secret door in operation. I took the videos with my phone at the time, so they're not the highest quality videos, but they're all I have of this particular project.
