Google launched a new website Google Art Project, created in collaboration with 17 major museums around the world (these included the Hermitage and the Tretyakov Gallery). It shows part of the pattern of these museums in high resolution (and in one picture from each museum's digitized at all with a resolution of 7000 megapixels) and also given the opportunity to "walk" between the pictures of individual rooms of the museum with the help of Google Street View. It is planned to increase the number of partner museums.
