MultiPoint TUIO is a tool for developers to test applications that make use of Multi-touch trackers that broadcast data using the TUIO protocol. The application is built for Windows XP / Vista using the Microsoft Multipoint SDK. This enables the user to interact
with the application using multiple pointer devices, just like the Microsoft Surface SDK. This tool eases the process of building TUIO applications as it removes the need for testing your application using a true Multi-touch device. Take a look at http://multipointtuio.iamhigham.com/
