The cameras they use on this project are absolutely incredible. If you know what you are looking for, you can really gain a new appreciation for works. The only two downsides I have seen with this project and ArtFinder is that 1. They seem to focus on Modern Art and earlier, and are really weak on contemporary challenging artists. Meaning you can't really interact with artists you read about at Frieze etc. and 2. I still find it hard to just get pleasantly lost in the work - Quite often it is a chore to discover things you actually care about, and the "fun" of wandering around a museum wears off quite quickly.
would love to hear people's thoughts.
