A video of C3Loops in action is shown above, and here’s some blurb on C3Loops from the website:

The C3LOOPS prototype was create in the resarch project Creative Activites Framework for Content Centric Interaction Techniques (ConCentric CRAFT or C3). The driving vision is that information content is the base for all interaction between users and the systems. I call this concept content centric interaction. Users conduct their activities in an unbroken creative flow.
Collaborating laptop musicians and video artists use C3LOOPS in real performance situations using monophonic touch screen or keyboard-and-mouse. The computer is a surface onto which all the user’s’ information content is visualised; the surface can extend to infinity like a magic paper. Surface interaction permits content centric computing, where content of different data type is moulded into blended media.
