I was outside smoking a cigarette I live next to an airport so I am very confident at my eyes when I see aircraft which land there. It is a small flight school with only small aircraft. As I look to the northeast I see what appears to be a formation of 3 diamonds wich all appear to be connected it was traveling silently and slower than landing airplanes. As I look at the object the diamond split into 3 separate diamond objects. They have flashing lights of all color or hue. At this point the diamonds begin to change shapes each triangle,Diamond,Cigar shape each independent of each other. I have a spotlight in my back yard so I shine it at one of the objects which darted forward and backwards and left to right each darting to evade the light I was shining. As I watched the shapes seemed to rejoin into one large diamond and in a large flash of color and no sound shot directly into the sky with lightning speed the total of my encounter lasted 15 min roughly.
