For this party, B.Y.O.K. Bring your own Koan on a card with a one word signature. We can meditate on Koans throughout the evening. We'll do other stuff too.

I was going to have you bring stones for a Zen garden but Zen gardens are for the slow, meditative school of Zen - it could have made for a boring party. Plus, Rose Anne was a bit worried about the location of the garden.
