One solution is the "Venus de Milo" approach pictured above: a capacious room containing a single blockbuster object, allowing many visitors to stand and circulate throughout the large space. Extra elbow room is especially important when so many visitors are using audio guides that lead them to spend one or more minutes looking at the object.
Another solution is the "Rosetta Stone" setup pictured below. Here the stone is displayed in the center of two intersecting galleries, protected by a glass case. This places the object in relation to the other materials nearby — in this case, other Egyptian works in stone — and therefore nicely contextualizes the piece. A concomitant drawback is the relative lack of space for the many visitors interested in such a famous piece. It's a difficult problem of spatial engineering which, if the predictions in the NYT article can be believed, will only become more pressing.
