I just wanted to remind the list that registered members of SDG have access to the Povray Koan Database (http://superdupergames.org/povray). (It's currently restricted to registered users since I offer the ability to generate new koans, and I need to have some control over the rendering resources. It's free!) It currently contains over 37,000 koans in 38 different series. I have recently updated the search engine to be much more useful. If you like to play online Zendo (at SDG or anywhere else), you may find the database useful. Cheers! Aaron
