MacRuby is a pretty interesting project. I'm not a huge ruby fan, but it definitely does have some syntactic advantages over Objective-C. Objective-J is walking a similar line, and thanks to its JavaScript base it has many of the same things MacRuby brings to the environment. MacRuby probably has better immediate performance potential, but Objective-J has more flexibility in future language design decisions. It's a good time for those of us interested in Cocoa and its related projects.
