Photosynth is a powerful set of tools for capturing and viewing the world in 3D. You can share your creations with your friends on Facebook, publish them to Bing, or embed them in your own blog or Web site.
Photosynth is available on lots of different hardware but I Ioved using it on my recent trip to Pompeii and Rome on my mobile phone. As an educational tool it really brings things to life. I'm hoping to use the images I made as well as the much better images other people have uploaded to the website for History and Geography lessons. Give it a try, it's free and amazing!
Here are a couple of images made using Photosynth (not mine) but to really engage with the images click on the links below to see the images I took in more detail, you can navigate and zoom in on the picture too!
