Five3D is another entry into the Flash 3D arena, but with an interesting approach – all vector graphics.  Currently implemented in AS2. I’m tempted to download the package, but I already have too many background projects 🙂

For the right application, it could be very useful tool.  Check it out here.

Update: If I had just visited Zeh Fernando’s site, I would have seen the link to the Five3D Lab.
