We did a show on Zendo a while ago, but there doesn't seem to be a forum thread for it!http://frontrowcrew.com/geeknights/20120515/zendo/
Tonight on GeekNights, we consider the delightful Zendo. (The most efficient way to purchase it is via multiple copies of Ice Dice). But first, we ramble about clipless pedals, JeepAthon2k, Nintendo's woes, the Portal 2 Testing Initiative, Valve hiring hardware people and considering a "steam box", and even the opening to Eretzvaju.
Also, this episode was recorded some time ago (as Rym is traveling to Istanbul), and at that time PAX Prime was not yet sold out. We must have been prescient.Growlanser: Wayfarer of Time opTwo Best Sisters Play Portal 2
We now also have video showing you how to play.
On a related note, I played Zendo at a board game party for my University's Physics Department, they applied Set Theory to the problem, best night of my life.
