ClarkEvans, who is a member of the Design Patterns Study Group I run in New York City, recently told me about his work with JOS. I think the idea is great and I'm glad to lend a hand. I've been working with Java since it emerged out of the Sun labs, and I've built some interested all-Java web sites with it.
I'm always amazed at how few people know about patterns, especially when they are creating languages or consumer software products. So I am glad to see how many folks in this community are patterns literate.
