How do these lights work? They’re only showing light where the shadows are?

How does the technology work? Should the lights be blanketing the entire table in light? How is there light appearing only from where the lights are not?

I shot some video at CES because I thought it looked cool but it wasn’t till after I left that I realized they are only creating color where the shadows are. There were three lights from the lamp above the table. The company I *think* is part of Panasonic (they were under the Panasonic sign). The logo I remember having “RGB” but I can’t find any other info about them.

There are three lights. Each of the lights is in a different place. When an object casts these three shadows, they don’t line up because the three lights are in a different place. The shadow of one light shows the other two, unless it intersects the shadow of a different part of the object, in which only one light makes it to the table.

This is basic physics, beautifully demonstrated.
