Just to be the Devil's Advocate here...I'm wondering if it's an electronic hot-air balloon consisting of one of those fluorescent light changing
technologies in a cloth (yes, it is very possible considering invisibility cloaks used by the military) with a black plastic bag attached below. The
blowing wind would results in a contortion of the bag, while the light-cloth (for lack of a better term) would consistently change colors.
This could perhaps result in the images seen above.
Or...I could be totally wrong, and we've just been Rick Rolled by a super-intelligent species.
