MagToo is a useful online application that lets you create great looking 360 degree panorama shows. These slideshows can be shared via flash widgets on other sites or social networks.
You can create panoramas by uploading all your overlapping images and stitch them together. The site won’t work in Firefox, it implements an active x control so you have to open in IE and install Active-x controls for this site to work. Once created, the panoramas can be shared with others by embedding on social networks using flash widgets.
Magtoo also allows you to create simple slide shows from your photos apart from panorama shows. You could show these cool shows on a google map to create a travelogue.
