Bay seniors who thought they wouldn’t be wandering the galleries of the Met, the Uffizzi or the Hermitage anytime soon, may now go there right now. You’ll find 17 world-class museums at the Google Art Project. Visiting hours are 24/7. There is no admission fee. There is no irksome audio tape telling you you are looking at a Van Gogh. Navigating through the galleries requires advanced zooming skills. Have a look.
