Bounce - Screen Captures Shared

http://www.bounceapp.com/
Bounce allows you to make annotated screen captures of websites and then instantly share those screen captures with others. To use Bounce, type in the url of any website then click "Bounce." Bounce will then create an image of that website on which you can draw boxes and annotate those boxes. You can create as many boxes and notes as you like. When you're done creating notes, Bounce will provide you with a unique url for your screen captures that you can share with others. If you create a Bounce account (optional) you and other Bounce users can annotate the same screen capture.
