@michelle if the video is not a fake - it really looks, also the movement, as if this was a humanoid or something similar, with wings, landing on its feet and then pushing off again. and fast! :-D
on what things look like: we live in a 3-dimensional world and our perception is limited to 3 dimensions. so if we get a look on something / somebody existing in more than 3 dimensions, we cannot encompass all aspects of it/him like we are used to. So it may be looking totally different from a different "angle". Like, if you were living in the "Flatland" (like Sheldons Flatland in Big Bang Theory) and knew only 2 Dimensions an then a 3Dimensional beeing sticks its finger at you. you cannot perceive a 3dimensional finger but only the front or, when it turns, the side - and it would be difficult to see that this is even 2 views of the same thing.
a bit srewed up theory, but I think, that is one of the problems of seeing supernatural things or what does not belong in this world. our brain cannot process what it sees, so it has to translate it into something it can digest. so you get a simplification, a metaphor a "flatification" :oD or something like that.
but about the theory of the merkaba beeing the same thing as the wings - why then does it feel like wings and not like 2 counterturning fields? even if we cannot percieve it with ou r eyes, we should be able to feel it, or what do you think? Or, perhaps of 3dimension restriction you can only feel the one or the other at the same time ... (I'm getting carried away...)
