This app is great !!

If you are related with the art world,you must know "Google Arts & Culture". It´s a great app where you can serch a specific artwork in HD. From the Gallery, users can zoom in on a particular artwork to view the picture in greater detail. You can even zoom to the point where you can see the brushstroke of Seuret in "A sunday on la Grande Jatte". It's amazing!!

Also users can log in with their Google Account to create their own collection and these artworks are protected with copyright. It is really useful to assemble your artistic portfolio. 

The proyect was launched on February 1, 2011 by Google and it´s  great, I can find masterpieces in a really good quality. However, there are many artworks that are not in the app. 

Every day Google updates the app, the platform now features more than 32,000 artworks from 46 museums, and image acquisition is underway at the remaining partner museums.  Someday, perhaps, all artworks will be in the web for us.
