NUI (Natural User Interface) recently unveiled Gravitoy, a multi-touch physics application that offers two modes of interaction. Below is a picture of children engaged in collaborative play on an interactive table running Gravitoy in the Sandbox mode. The children can draw objects that interact using principles of physics.

Below are table-shots of the Sandbox mode:
See the triangle?
The second mode of Gravitoy is "Stacks". Two players play a game of stacking objects of various sizes. The difficulty level can be adjusted by changing gravity options.
This would make science lab engaging for students!
In addition, NUI developed a 3d model viewer application, which looks like it would be fun for budding architects and designers.
Visit the NUI website to learn more about the company and NUI's partners.
Take a look at Multi-touch Space Invaders from Multi-touch Barcelona. It looks like a fun game to play during a rainy recess:

I recently learned of another "open-source" touch-less "multi-touch" resource. The Touchless SDK was developed for a college project by a Columbia University student, Mike Wasserman.
You will need Visual Studio 2008, the code, and a webcam to get started. From what I can tell, the code will work with in the XNA development environment.
The Touchless SDK website has links to a video demonstration, demo code, FAQs, and more. The discussion list has a lot of good information.
Mike Wasserman is now working at Microsoft Labs.
