3D Background?? Is it possible?

[dsaundry]

Ok; Silly questions. Is there a product you can buy, build or steal, that you can put on the back of your tank to give it a 3D look with ledges etc?
I have seen the similar ones for reptile tanks but I would like to know if anybody else has done it in a reef tank and to what degee of success.
I have seen the 3D stuff online and it looks nice but it is all for freshwater, I want to know is there a place where you can order sized or cut to fit sheets of saltwater reef looking background or what material could you use??I think if i is possible it would be a great way to disguise intakes and jets etc. Sort of like a false wall, so to speak. Also what would be the possible problems of a system like that?
