The Tigertail Virtual Art Museum simulates the experience of walking aroundan actual museum, complete with a floor plan that you follow to find works from Egyptian, Renaissance, Modern, and 20th-century periods. But, unlike regular museums, the Tigertail offers restored versions of art so that the viewer can see how the original work looked or was possibly intended to look. (The Tigertail’s Leaning Tower of Pisa, for instance, does not lean, so that its original design may be examined.) You can also find art history and interesting facts about art maintenance. The museum is partially funded through its affiliation with Barnes and Noble, so the occasional advertisements may be somewhat annoying. Beyond that, the museum houses an impressive collection and displays it beautifully.
