Mannekins answering questions...sounds absolutely awful. If you want to provide "canned responses" to common questions, a computer interface using some sort of hypertext would be better. You give up the phoniness of the mechanical people, and give some control to the visitor as to what questions they might ask. Then the "canned" responses can use graphics, photos, sounds and they can be revised, added to, deleted relatively easily.
