This is the interactive Prototype of Scrolling 2.0, a concept for the Spring 2009 Mozilla Labs Design Challenge, by Valentin Laube.
Instructions:
click on the flash animation to give it focus
hold the space bar to activate scrolling mode
click the scrollbar to scroll to the desired position
drag the screen to scroll the page
secret: if you hold shift+space you can see the widget for my other concept which i didn't finish in time. theoretically you could switch tabs and browse the history using this interface. see this description for more information and a picture illustrating the concept.
