Here is yet another very helpful, very cool tool for teaching art history. I actually found out about it in History of World Art II here at UMD. The Vatican Museums website (http://www.museivaticani.va/) has a feature that brings you on a high-quality virtual tour of the Sistine Chapel. The zoom-in tool is fantastic - you can closer to Michelangelo's famous painted ceiling than you could if you visited the chapel in real life. This virtual tour allows a class to view this magnificent piece of art history without taking a very expensive field trip.

The tour was great! I think with something like this you should have an assignment related to it so that the students remember this piece. Maybe different groups could pick out one part of the chapel to research. This could be the tool used to let them navigate to pick out a section.
Great Find.
