From the competely-useless-but-why-not department: Tilt is a Firefox addon that lets you visualize any web page in 3D. A new update is available, coming with more developer-oriented features.
From the Tilt page:
A requested feature was the ability to export the visualization as a 3D mesh, to be used in games or other 3D editors. Tilt adds the ability to export to .obj, along with a material .mtl file and a .png texture (a screenshot of the entire webpage). The open .obj format ensures the fact that the mesh can be opened with almost any editor.
