Mounting a screen to a vaulted ceiling in front of a flat panel TV

Hi, I'm going to be purchasing a screen from monoprice (I don't have the skills you guys have). I need to mount it from a vaulted (pitched) ceiling. I want to mount/hang it in front of an LCD TV that is mostly used for XBox gaming by my kids. The idea being that we'll lower the screen when we're ready to watch a movie. I can't find any mounts. There are plenty of mounts for the projector. How would you guys do this?

I was thinking some kind of circle type hook into the joists with chains hanging from them. I think that will look like crap though. Any other good ideas?

Thanks

I used small carabiners and multiple metal links with a screw that allows you to lock the link closed (not sure what they are called) attached to hooks mounted in the studs in my ceiling. It ended up working really well.
