Well, then I decided to do one. And while doing it I noted what I was doing and created an action to complete all the steps should I ever need to do it again.
The action copies the original layer, then the layer gets desaturated, duplicated, the red and cyan layers are created, the two desaturated image layers are offset, all the layer blend modes are set, and finally the image is flattened.
The action file can be downloaded here:

NOTES
As can be seen I had to 'hand crop' the image to remove the shift (which can be seen in the second image as green in the bottom-right corner. No matter how I tried I could not get the action to crop different size images - so I just use the crop tool after.
Supposedly, the 3D anaglyph effect can be obtained on a color image (without the desaturated image adjustment); but the color values change so much it is an individual, per image, thing rather than an action.
