before ideas, do you have a limited budget so we know what kind of items would be feasible to make this work? Is there a specific price range you do not want to go over? With that we could maybe pick out specific items as well :).
The first thing that popped into my mind was a GOOD set of speakers. Second I have always like really big monitors, like 22" or something like that. Projectors can be nice, but are a little on the costly side. IF you want something big here is a 60" monitor for $1400 ($600 off): http://www.newegg.com/Product/Product.aspx...N82E16889005095. Unfortunately it does not have free shipping, but it is still fairly cheap for that size. The average 1080p projector is gonna be around to $2000 or above, but I don't know what yuo had in mind. I am sure there are others but my mind is blanking right now. Probably due to a lack of sleep for 3 weeks. If I think of anything else Ill post it. But if you do have a price range, please tell us.
