MIT hosts AppInventor, which was previously a Google project. It is still active and was recently updated. AppInventor has a somewhat cumbersome GUI which is not suitable for advanced programming, but you can get things done. Furthermore it is a platform for teaching kids how to program. As many other programmers I wish there was a possibility to export to an Eclipse project and/or an option that made compilation for iOS possible.
Have a look at my app made with advanced usage of AppInventor: Homepage
