This is an image that was created more or less by accident.
This free Photoshop filter is created by Richard Rosenman and it works like: put a photo in and an abstract work comes out. I mirrored the result, converted it to negative and then provided a yellow/brown color layer because I didn't like the original colors.
Tried this 3D filter, but didn't like the rather strange effect I got with a normal, sharp image.
After some experimenting, I opted for a blurred photo to create this 3D effect.
It looks a bit like reflections in steel, silver etc.
