Lighted, bobbing and weaving (like a game) moving North to South through clouds

2 craft moving quickly. Other witness saw first then pointed them out. Color was off white, possibly due to cloud covering, and of consistent and solid brightness. Both craft had more of a boomerang shape. They stayed close together despite cutting in front of each other as they "played." No sounds, no blinking lights, have not seen before and have not seen since. Isolated incident. Clouds sat a little low that night. What we saw would have been towards the bottom of the clouds but not under them. Thought possibly there was some sort of light display for kiddos to think Santa was on his way but saw no reports of such and did not see the objects again.
