Bonsai & You (tube): Mixed Gallery
This is a collection of images that someone put together. I recognized several trees, including at least one Kimura (The Magician), one Morten Albek (author of Shohin Bonsai), and one Wolfgang Putz.
Overall the quality is very good, though a few fairly ordinary trees found their way in.
