If you haven't been keeping up with Geoform this would be a good time to visit. Geoform has grown to be an important resource for geometric painting and 3D works. The site features images, information and interviews on a large number of artists from around the world. It was developed by Julie Karabenick and Howard R. Barnhart, both artists who I have had the pleasure of exhibiting with.
