Der Zahlentisch (the number table) is a brand new interactive installation by ART+COM for the new 10+5 = Gott exhibition in the Jewish Museum in Berlin. It‘s a really nice user interface and works really well. Check out this movie to get a clue.
The system is running on Windows, is programmed in Java, using OpenGL via JOGL and QuickTime for movie integration. The user interface uses capacitor foil to detect the peoples hand movements.
