Thanks for this link to Concrete Abstractions. It looks great. I downloaded the pdf and plan to explore it. <div><br><div>Yes, I'd like to build a Cobalt world. That sounds like a good idea. I figure that's where the active development is, and I should be. But I made a few inroads with Croquet and just sort of played around with it more. I'll email you tomorrow. At the moment it's Friday night and I need to turn off my brain. </div>
