UFO Sighting in Baton Rouge, Louisiana on December 11th 2002 – Lights appearing forming shapes, disappearing

I was at work on a construction site, after my lunch break. I happened to look up and see 3 red lights above me, very high in the sky. I called to my co-workers to look at it because they were moving slowly. They formed a triangle shape. My foreman said it looked like parachuters but they never descended. As I watched the 3 lights slowly move, other colored lights appeared out of nowhere on the periphery of the triangle. These lights were blue and others were yellow. It seems that there were 3 of each kind of light. The lights then began to form other shapes, as if they were dancing into a rhythmic formation. This went on for 5-10 minutes as the lights slowly moved about and changed positions. Then the lights started to break off and move away, disappearing from site.
