Interesting - Make3D - Convert your image into 3d model

Make3D converts your single picture into a 3-D model, completely automatically.

It takes a two-dimensional image and creates a three-dimensional "fly around" model, giving the viewers access to the scene's depth and a range of points of view. After uploading your image, you can "fly" in the 3-D scene (requires VRML viewer or Adobe Shockwave), or watch a rendered 3-d movie (flash required).
