AT texture

wow. i love this. actually all your variations draw me in. i think this one is the best for me, i think because of the swirls on the "shell"? bottom right relating to the shapes on the left side of the photo. i also tend to take photo with a corner fading out to white, so the fact that this one does that somewhat also makes me like it a bit more than the others. (luckily i can still enjoy the others even though i've chosen this one to make my comment on.)

and what is the object on the right? i'm so curious. feels natural, but it must be manmade, yes?
