Basically yes. (You could do without a projector actually.) Additionally you need the cubes which are printed with special patterns (Fiducials) so that their positions and rotations can be read correctly. You could then for example use the "reacTIVision" software to read from a V4L-device and generate OSC-messages according to the patterns that have been recognized, or use the [pix_fiducialtrack] object to analyze a video stream with fiducials in Pd/Gem.
