Need a little inspiration? The GlassArtists.Org gallery has images of over 30,000 works by over 900 glass artists!
Listings are browsable by category (architectural, carved and etched, fused and slumped, glass beads ... you get the idea). The site also maintains listings of galleries and glass-related organizations as well as chat and a message board.
Perhaps best of all is the fact that any glass artist can create their own gallery on GlassArtists.Org for free.
