Oddly shaped object that flew at a angle

The odd shape object came from the east and had multiple lights of different colors. It moved quickly and as I stood in my back yard and watched it it appeared to come over me and I was able to see that it was not a plane or helicopter. It was shaped like a diamond but a angled diamond. At each of the points the lights were different colors. One point had a blue light, one had a red light, one and had 2 white/yellow lights and the last had point had a yellow/white light. the lights also intermittent. There was also a subtle sound. As it came across the sky it glided in the sky to the right, I did not see it fly straight forward
