I was browsing the teacher blogs I read today and came across a post about Google Teacher Academy (sounds like an amazing PD opportunity!). Among the cool stuff this teacher shared was Google Art Project. This is an amazing resource of tens of thousands of gigapixel images. And what's even more awesome is that you can search by just about any parameter you can think of: not only by collection, artist, and medium, but also by event, place, time, and person (artist or subject). This would be awesome for social studies and who knows what else!
