I fail to see any real developer connection...

It's for web design, as says in the tags: how-to, reviews, tools, web design

Lively can be inserted in any website, and 3dxplorer too, it's a Java applet, and has a programming API available.

Thanks greenIridium. I think, they are very informative. Especially, I was wondering about Lively. I haven't tried it yet. After your comments, I decided to wait for some to try it.

Thanks to you. If you read the comments on the post, you'll see that Omind tried it with a Quad with 2 graphics card and 4 mb of RAM and happened the same.

The second part is not developer related but if you want to read the review of 3 more, go here:

The exception is ExitReality that can be used to embed your 3D world or turn your 2D page into a 3D world.
