Odyssey.js is a new open source map creation tool from CartoDB. Through Odyssey.js you can create mapped stories in three formats; slide, scroll, and torque. In all three formats viewers will see a location on a map along with the text and pictures of your story. The slide and scroll formats are fairly straight-forward, you click through slides or scroll through a story. The torque format allows you to connect elements of your map to a timeline.
