I have been working in instructional technology for the past 10 years. During that time I have experienced the development of some amazing instructional tools. The Google Art Project goes directly to my "best of" list of innovative web-based tools!
The Google Art Project uses Google Earth street view technology to allow visitors to take virtual tours of the top museums in the world. Visitors can navigate the hallways, zoom in on art work to see the details of the brush strokes, view information about the artist, and build a personal art collection. There are so many great features to this site . I embedded a YouTube video that provides a short introduction to this site. It is well worth the three minutes it takes to view it. The video is from YouTube so if necessary you may to use a firewall override? (Jefferson Teachers please use your firewall login to bypass the filter)
Here is the link to the video: http://www.youtube.com/watch?v=GThNZH5Q1yY
