This effect was generated in Filter Forge, a Photoshop plugin that allows you to create your own filters.
Creates a pseudo functional anaglyph image.
At present, this filter works well with the default preview image because a simple height map is generated for it.
However, this filter could be modified to accept an external height map and then it would work with other images.
Control Overview:
Height Map Dist. - Controls the strength of the height map distortion.
Separation - Controls the amount of separation between the red and blue channels. (50 = No Separation)
