Interesting enough?

It took me a second to figure out what it was. I was immediately drawn to the dark areas and saw a pattern of triangles, and couldn't figure out what they were for a moment, until my "perspective" shifted and I realized what I was seeing; I love photos like that.

Thanks for your comments. Your response was exactly what I was striving for.

Wow, very cool! Well done! Take care

this is realy amazing, i love that it looks more like a textile pattern than a photograph until you look at it properly.
