The Prism Convention: a new approach to classifying currency design

In light of recent developments in currency design, such as the tentative announcement today at the NCF blog, I have decided to publish an early draft of a paper that I have been working on. I am glad to see an increase in activity that shares more or less a similar design philosophy behind the Prowl demonstration.

Please post or send in your comments, questions suggestions and/or objections that could help improve the paper.
