Yellow jellyfish shaped light bouncing around in the sky during the day, when the sun was out.

There were 3 people staring into the sky, pointing, and taking digital pictures, at a local hotel pool that I was at.  Some of us ran over, and the object that they were looking at had disappeared by the time we got there, but one of the guys had taken a small video of it, and some pictures on his digital camera.  It was yellow, like a light, and seemed to jump around in the sky.  Up, down, to the left, right, diagonal, etc.  This was during the day, and the sun was out.  Then it just disappeared, as if someone just turned off a light.  It sort of resembled the shape of a jellyfish.  Two of the people said that they had seen it earlier in the day.  I was waiting to hear about it on the news, but I never heard a thing.  I've never seen anything like it before.  Of course, a few of the people thought it was a reflection of something, or a military something or other.  I just don't know.  It also looked like there were little lights on the light itself.
