A final notice everyone -- if you have some projects sitting around in App Inventor, and would like to keep them, either for some crazy time-capsule experiment or in the hopes of migrating them to MIT's App Inventor project, you've only got a handful of days left. Come December 31, Google will be taking the whole kit and caboodle offline, and projects that haven't been downloaded are lost forever.
Getting them is easy, just log into appinventorbeta.com and hit the "Download All Projects" button as shown above. Keep them safe, and when MIT gets things back up and running in 2012, you're ready to go. For more information about MIT's implementation, have a look at their Learning Center.
