    This is not so hard.

    Say you have a laser on scanners watched by a camera.

    Its moving >>>>>>>>>>>>>>>>>*

    It hits a black spot B

    B

    Look at the 3x3 matrix of pixels around B

    xxx
    xbx
    xxx

    Say it finds this

    XXB
    XBX
    BXX

    Is it left or right handed?

    OK, Its leftie,

    So move up and scan around the 2D matrix. Turn accordingly.

    Repeat process. Add some code to deal with noise or if objects are isolated.
    If you have enough memory, store the center of objects in ram so you can speed things up.

    Find the version they did that runs much faster! Each shape has its own distinct sound.
