Plans for an elevated layout?

[hunter2115]

I've seen and heard alot about using pulleys and cables to build a layout that can be raised and lowered- to and from the ceiling but I cannot find any detailed plans on how to build one. Not being particularly well versed in engineering, I'm wondering if anyone has any plans or articles for doing this?
I would certainly appreciate it if someone could point me in the right direction on this.
