The Lost Museum

Museums on the web are, in general, rather disappointing. At worst a selection of digital images with directions for how to get to the institution, at their best, they use the potentials of the internet to create new online visitor constituent (see the Brooklyn Museum’s Myspace page for instance,
Possibly one of the best ‘virtual’ museums, The Lost Museum is a digital recreation of P.T Barnum’s American Museum in New York, which burned to the ground in 1865. Visitors are encouraged by the man himself to solve the mystery of the fire. You can explore the museum in three-dimensions with innovative use of image, film and sound, search archival material, maintain personal files on the case, and engage with specific objects. There is also a classroom section for linking into classes on American history, Museum Studies and material culture. The project was created by the American Social History Project/Center for Media and Learning at The Graduate Center, City University of New York in collaboration with the Center for History and New Media at George Mason University.
Any other recommendations for really good ‘virtual’ museums? Or comments about museums on/in the internet?
