    As much as for tracking it is an object in 3D in the scene that you know the dimensions of, a lot of data can be derived from that and a similar object can be placed in the scene with CG to check against it.

    Very unique kit consists of 3 circuit boards that when assembled form a 3 dimensional flashing LED pyramid. This mysterious and amazing kit features 47 bright LEDs that flash at a rate that you can adjust using a small control. Operates from one 9V battery (not included) and uses a reliable one IC circuit. The pyramid is about 3” high and has a 4 1/2” base. The pyramid is hollow inside and can be set on top of the 9V battery to conceal it.
