Thanks for the comments, guys.
I originally intended it to be nothing more than a background but your suggestions got me thinking about taking it further.
p?tr??k, the technique involves using layers that alternate between lighten and darken mode. There is plastic wrap, tranform/rotate, and wave used as well. Basically, each layer is a variation on the layer below then either lightened or darkened to make the object to appear to have depth. I then used the lighting effects flter to add additional height and emphasis.
I did a write up of a similar effect I called giger but it has scrolled off the forum. I'll see if theKeeper still has a copy.
