Not always. For me this image draws you in and down. The repeating light shapes on the left draw you in and your eyes come to rest in the abyss leaving you with an emotional response as opposed to visual satisfaction.
Yes, the angle makes it work. I've been content looking at the detail on the left side for a few minutes, so for at least that long it hasn't become boring. I did find myself wishing the highlights were a little lighter, but that could possibly be my crappy monitor here at work.
