I've wanted to do something like this for awhile. I think the better way to go is to incorporate this into a new web browser. Put in an algo to generate a 3d space for a website from it's html but also allow site owners to build specific 3d versions which are specified in xml. <p>That way you can browse the entire web in 3d (although pages with pictures would look more interesting than say... Newsy ;) and stores, game companies, whomever can create fun 3d worlds for their visitors. <p>If you could do some clever look ahead you could even make links into portals that show you what the next page is going to look like in 3D. So if you link me to a World of Warcraft page I can look through the link and see what that site looks like. Walk my avatar into the portal and I'm on a new website.
