Hey guys, don't know if you already know this site, but I thought it would be good to share:

http://www.artofimagination.org/Pages/Gallery1.html

There are so many fantastic artists and pictures of their works there! Check this guy, for a start: http://www.artofimagination.org/Pages/Smorenburg.html
When I saw his paintings, I almost jumped out of the chair and hit the head on the ceiling hehe.

Hope you enjoy the trip.
