Google Wave is a new online tool that provides a platform for real-time collaboration and communication. Google has combined features of instant messaging, wikis, email and word processing so that users can work together to create and edit documents called “waves.”  These waves allow any participant to edit any part of the document and there is an option to add pictures, maps or graphics to the document. This tool could be useful for collaborating on group projects, brainstorming, class notes or even planning an event.

Initially Google Wave only released in a limited preview to a select number of participants, but now you can follow this  link to request an invite from Google. It still may take a few days to get a confirmation email though. For more information about Google Wave visit their website or watch a short video from some of the Google developers.

As of August 2010, Google Wave has been shut down.
