a free, downloadable browser that renders the web as a 3D city or store of display windows, each showing a different site or product. in contrast to hierarchical editors (e.g. Yahoo: Levi's is positioned under the category Business > Apparel > Casual > Denim) this 3D browsing interface uses self-organization to catalogue websites, as it leaves it entirely up to the site's owner to decide their best position within the city (e.g. Levi's next to MTV). virtual location selection is managed similar to commercial property development: site owners bid against one another for their favorite locations, & can re-sell their locations in a free market.
it is claimed this 3D city metaphor is more effective & 'better than Google' for advertisers & users because it relies on visual discrimination, rather than keywords & logic-based searches. [3b.net|thnkx David]
