Holographic effect! Help!

I have tried to search for a technique on this effect. I'm still trying.

I gave this one a try. I guess this is a start in the right direction.
1. Image of plywood. Make a duplicate of the BG layer
2. Apply liquify filter
3. Desaturate the image and set white point with curves
4. Go to channels.
Make a selection of the Red channel and move it to the left 20 pixel. Delete this selection.
Make a selection of the Green channel and move it to the right 20 pixel.
5. Motion Blur filter, 90 degrees, distance 90.

As I recall, a similar request was posted here a year or two ago, and no good solution was offered, so I decided to do a bit of digging using other terms for the same phenomena, particularly, "strain induced birefringence", "photoelasticity", "photoelastic fringes", etc.. Here are some good examples of what this looks like in the real world (ie, not simulations of the effect). The first link is particularly beautiful, IMHO:

However, when I did a search of the literature for simulations of the effect, surprisingly little turned up. There is one guy in Korea who has put out quite a few papers on it:

http://www.bibsonomy.org/bibtex/2fa45855925bbda5a2926a655681e15c6/dblp
And very few by other folks:
http://www.sciencedirect.com/science/article/pii/S0168900209003660
The above simulations were all done using mathematical modeling of the physical processes involved using numerical programming languages like Fortran, C, Matlab, etc. I didn't see anyone try to make visual approximations of the effect in PS.
So, if you are limited to PS, I think the best approach for a visual artist might be one similar to what Chris showed. Another approach might be to take a real strain pattern and then liquify it to the shapes you desire. Obviously, this can also be supplemented by rotation of the hue of the colors in the image, but if you want it to look real, the colors produced by real world samples are usually quite similar to what you see in my very first link.
