UFO Sighting in Austin, Texas on July 11th 2015 – Cube-like oscillating formation floating on tilted axis over rooftops.

I was standing upstairs (3rd story) in a condo in the Brodie Heights subdivision on Davis Ln. I looked out of the upstairs bedroom window which faces west and noticed a cube shaped formation floating about 50 feet above the roof tops at about 20 to 25 mph. The formation consisted of 5 cube-like objects tilted on an axis with one cube on top, 3 cubes rotating or oscillating like an orbit, and one cube on the bottom. The top and bottom cubes did not appear to be spinning or orbiting as the progressed in a straight line northward through the sky. The color was brownish tan or copper. This occurred at about 7:40PM CST, which means the sun had not fully set and there was still a good amount of daylight. I did not observe any lights or hear any sounds (though I was inside with the windows closed). Because the objects were moving so quickly I did not have time to run downstairs for my phone or a camera. I called a friend over to the window and he also witnessed the formation.
