i made a patch that maps 16 fiducials of the reactivision software:
that patch basically makes 1 bang when you add a fiducial, makes 1 bang when you remove one, and maps the xpos, the ypos and the angle of each fiducial when they're on the table.
it allows you to start a reactable like project.
i thought it would be cool to share that patch. it's working quite good here :), but if you have some comments, feel free to give them, i'm a newbie in max/msp, so i'm more than happy to learn.
oh: you'll need to install the Tuio_client external,you can download it on the reactivision website.
