Okay, let's see how portals work in practice

Thanks to TechCrunch for this pointer to Just Leap In. Hard on the heels of the demise of Lively, this virtual world seems to do a little better: a real physics engine, user-customizable spaces, and what sounds like a simplified version of my ancient Portals proposal -- that you should organize a virtual space in terms of attaching gateways from one place to another, rather than trying to make it all a simple real-world-like 3D space.

Of course, it's still nowhere near the Braid -- centralized servers, not apparently open source or protocols. So I'm still skeptical. But I wish them well, and it'll be interesting to see how people react to their "doors" mechanism...
