    So if I wave a loaf of bread in front it will tell me how much it costs?

    No, but it will cut it into 12 nice slices and they'll be ready toasted

    NUVO is a local arts/events magazine.

    They came by yesterday to interview me about the laser harp and the hit count on YouTube - we managed to get some better pictures...

    Correct, there are no sensors above the player and the beams can go off into space...

    Borrowing Sebastia(e?)n Pamart's fab diagram...

    This is kind of how mine works, but with the right kind of sensor and some nifty electronics you can avoid the mirror with the hole in it and the lens.
