Mirosoft Live labs released Photosynth . Photosynth takes a collection of regular photographs and reconstructs the scene or object in a 3-D environment.

This first version of Photosynth has some limitations that you need to be aware of:

• All synths are uploaded. They're big, so you need to use a broadband Internet connection.
• All synths are public. Your photos will be visible to everyone on the Internet.
• Like the viewing experience, the "synther" only runs on PCs (XP and Vista).
• You'll need to Sign Up for a Photosynth account. It uses Windows Live ID.
