I have no idea what it is, but it sure looks cool lit like that. The only think I don't like is the narrow DOF - there's just not enough of it in focus to draw my eyes. After looking at it for more than about 5 seconds, I start to feel like my eyes are crossing and I can't focus!
beautiful shot. i can't help but think that a wider DOF might have been more effective for this challenge since the point was to show the pattern, but i like it anyway.
I love this, one of my favorites. looks like the reflection of a dying fire on the wire mesh in front of the fireplace. if that isn't what it is, I'm looking forward to finding out the right answer
