Over Ann Arbor Michigan sighting. Pulsates, colors

In the Northern sky, hanging out my second story window smoking a cigarette. When this appeared in the open sky. It was round and pulsated, getting big than small. Mostly blue with red and green lights. I saw this last year in January. So ever since then I had been waiting to see it again. When it showed up I grabbed my LG android phone and stated recording it. This is the video. The blue one I could see but all the other ones I couldn't see with my naked eye. Only on the phone while recording.
