Grafiti is a C# framework built on top of the Tuio client that manages multi-touch interactions in table-top interfaces. The possible use of tangible objects is particularly contemplated. It is designed to support the use of third party modules for (specialized) gesture recognition algorithms. However a set of modules for the recognition of some basic gestures is included in this project.

The development can be considered to be almost in the beta state.

The goals I've been aiming at are: generality, versatility, speed of execution, extensibility, ease of programming (integration) of external modules (simple APIs and protocols) and effective interface design with regards to HCI aspects.
