These sims are all very art related. Some of them change often and are places for artists to display work.
MIC - Imagin@rium - Now I know I have blogged this area before but I wanted to show you some additions around the edges. Make sure you venture further than the central island.
Lea25 - Sea of Cubic Dreams - This sim is amazing and I just put the environment setting on the one the sim provided and snapped this shot. Easy!
MIC Imagin@rium - Cool Greek looking ruins and buildings with art scattered in the water along pathways.
MetaLES - This is a sim created to celebrate and promote art and artists. Changes often.
