It's like two parts of one mind coming together in a way they were never quite meant to. On a philosophical level I find it quite fascinating. To some degree we're all concerned about how we appear to other people. Do they think we're smart, well-dressed, sexy? The idea of seeing ourselves, or kissing ourselves through our own eyes, yet as a separate entity. . .
I suppose it begs the question of can we ever truly love or even know ourselves?
And no, like Gwen, I didn't find the pictures the least bit disturbing. Although, I will admit I thought they were twins at first. I love the contrast between the seductive half and the startled, freaked out half in the second picture. It's a marvelous piece of photoshop work.
