Luminous energetic object tumbling/oscillating/rotating w/fast color pulsations/bursts. Fixed course, elevation & velocity. No noise.

I was having morning coffee on my western facing deck before starting my day, Friday May 12th, 2023 at approximately 4:45-5:00am. It was then that I observed an object in the NNW that I was unfamiliar with and watched it for a minute or two. It was on a linear course to the SSE. I thought I should try to capture some images with my smartphone. There is one video. I took some stills. Also included are some screen shots of stills gleaned from the video then enlarged. The video and the images are the best I was able to capture. I was a bit nervous so some shaking in the video. The object stayed on a constant linear path. The video shows about 1 minute of travel. Various images show the object in one state of 4 lights in a cubical or square configuration. Another image shows the other state of a multi color burst or pulsation. Still another image shows the view of the object that appears to look Chevron shaped. The object alternated these states very rapidly, approximately every half second between these states of appearance. While viewing the video in slow motion, the object appeared to tumble, oscillate and otherwise rotate. Which leads me to believe that different sides of the object were being captured in each frame. The object traveled from the NNW toward the SSE. I estimate the elevation to be higher than typical commercial and military jet traffic we normally see here from either the 103rd Airlift Wing (103 AW) unit of the Connecticut Air National Guard, at the Air National Guard Base at Bradley International Airport, Windsor Locks, CT or traffic into or out of Bradley International Airport. The course was linear at a constant elevation and velocity. My opinion is that the velocity was difficult to determine but seemed to move at a fixed velocity. From horizon to horizon it took about 10 minutes to traverse my field of view and I observed it closely for about 8 minutes. When the object was in closest proximity to me I took the video with my smartphone and some stills. It appeared larger and brighter than Venus which at early evening appears in the western sky here at this time of year. When it was in closest proximity to me, I was looking at it toward WSW. It was at about a 70 degree of inclination to the WSW horizon and not quite directly overhead. The gyrations and multicolored pulsation or bursts made it appear to be a very active and energetic object. There was absolutely no sound and seeing it was wondrous.
