Well done, That's a very cool project mate. Could I ask if the drawings on the little cards are picked up by max in any way? Could you explain a bit more about how this works? I made a project which is somewhat similar. check this out - https://cycling74.com/project/drawing-music-an-interactive-project-by-yuval-gerstein/

Very nice mate. Here is a project i did but in Pure Data. For future development ill try make advantage of Max. https://vimeo.com/43390253

Thanks for the kind words guys.

Yuvi - The drawings are merely there for description of what sound is played. The other side of each plastic "puck"has a fiducial marker on it, which is picked up by the ReacTIVision software. Have a look at their website for more information on that.
