the accounts of them being three dimensional and not flat is what made me wonder along this path of thought... (though its probably a silly thing to even think on for more than a minute...lol.).... but our world is made of color, it is how we see our environment. many shades of each color to form the whole picture before us. that along with a light source to add even more depth to the colors in the form of shadowing, from a light gray to a deep black....soooo, given that thought, (art 101, shadowing and perspective.....lol) any 3-d object casts a shadow as the light bounces off said object, but that has never been reported in this phenomena, which could be the reason of double explanations of both being flat 1 dimensional to also being 3-d at the same time......so was just wondering if in these cases is all light absorbed by these beings, or is something else entirely going on here...... yeah.... i dunno where im going here....lol
