Starting to learn about art (aka going to Museums, art galleries, reading art books). It soothes my soul. By far the most intellectual challenging activity I've ever done.
Would also love to hear about how you started learning, I've been working with a team on a product to try and make art galleries more accesible to "none arty" people so any pointers on the type of thing you found helpful would be really interesting.
Not quite although have a massive amount of respect for what the art.sy guys are doing. We (inguide.co.uk) are trying to put together a guide book platform which spans multiple art galleries and museums then learns about you and tailors the interpretation and info offered to the users level of expertise.
vist a museum and read the 'Agony and the Ecstasy' and 'Lust for Life' by Irving Stone. The first book is on Michealangelo and the second is on the life of Vincent Van Gogh.
