[Michlib-l] Ceiling projector?

Hi all, wanted to ask libraries with ceiling mounted projectors how those work. Toying with the idea of adding a couple to our meeting rooms, and I'm not sure how feasible that is. How are they hooked up for use? Do you need any other dedicated hardware (like a laptop) to use it? Would you say it has been worthwhile to have? Any suggestions or advice appreciated!
