Are we still doing this?

I checked out the NEH guidelines and a few things came to mind to make my project a little more “hip” as the kiddies say. Making the site a substitute for actually traveling to Dublin to see Kilmainham Gaol, requires giving the people experiences that they might get if they did in fact fork over the Euro to get there. I want to add a 3-D rendering of objects that are on display in the museum section of Kilmainham allowing the user to rotate the objects to see all sides of them. This would actually give the online visitor a more complete experience than the physical visitor, since the physical visitor can not touch. NO TOUCHING! Also I would like to include 360 degree panoramic views of various rooms in the jail allowing the online visitor to feel as though he or she is there.

I assume the technology for these kinds of things already exist but what are they called? How much do they cost? Does anyone know?
