The Google Cultural Institute website is new to me. It seems Google has a Pinterest, sort of. It appears to work in much the same way as Pinterest, but the pictures are drawn from images in various hi-res/open museum digitisation collections.
No ‘kitties in art’ collection yet, although searching for “cat” will get you a big kittie fix if you’re desperate.
Ah, it seems it’s a revamp / extension of the 2011 Google Art site, which launched with 17 gigapixel paintings and virtual museum tours… http://jurnsearch.wordpress.com/2011/02/01/google-launches-google-art/
