2 goups of 20+ haphazardly-moving spheres or obs circulating around each other2 groups of several spheres or orbs rotating around each other in a haphazard circular pattern. These appeared to be a flock of birds at first, but a closer look revealed no apparent wings or wing-based flying motion and there also appeared to be a metallic quality visible as they turned into their circle. The objects were circulating around in an unorganized 'follow-my-leader' kind of manner. I ruled-out a bird formation when the circular motion appeared to be around a minimally-moving general axis tending towards a north-westerly direction. There appeared to be 2 groups of these spheres/orbs - 1 group over the general area of Lake Forest and 1 closer west to the 5-Freeway. As traffic progressed I was unable to keep constant eye contact and could not see the spheres in their general direction some 3 or 4 minutes later.
