Query: Educational and Fun to Watch thse Glass Masters in Action!

Great PBS special showing Chihuly and his extremely gifted peers and students making all that tremendously beautiful glass art that those of us who know and love Chihuly feel such awe and admiration for. Any true glass art lover will enjoy this educational video which shows the glass blowers at work, from drawing to finished product. Recommended.
