Just wanted to list two websites that I've just recently been added into.
The first, Metalcyberspace, organized by Susan Sarantos, is a great collection of organizations, institutions, artist, and resources for metalsmiths/jewelers. I've been giving my students this website to check out.
The second is a European based website, dedicated to Rolling Ball Sculpture and Kinetic Art. Everyone needs to check this site out. If you don't find something that amuses you, then you're boring!
The sites are:
