A rough and ready demo to show related information displayed across adjacent panes in small, touch-based contexts. The pattern uses swipe.js with visual tweaks to hit towards extra information a la WP7. Swipe from right to left to see it in action
The demo is intended for small and touch-based contexts - it wouldn't make sense in your current viewport. Try opening on a touch device with a small viewport width - eg iPhone, Android etc.

A quick demo by Jordan Moore using the awesome swipejs.
