Make Rough Walls in Photoshop

[JFJohnny5]

Here's the results from some more testing. I think they all have merit. The "displace" ones use a displacement map, the names being the name of the file that is the map I'm using. The numbers refer to the scaling I used (both X and Y). The fourth one uses the crystallize method Ascension showed. For reference, the grid is equal to 50 pixels per 5ft. I think the two using the "displace2-softer" map work well for mines or other roughly hewn walls. The "displace3" map produces a more jagged edge, maybe an ominous underdark lair. While I think Ascension's crystallize method produces a very nice natural cave wall. And with Photoshop actions, these can all easily be applied at the touch of a button. Thoughts?

Cool... I have even done a bit of this to "tile" floors to make the grout/grid look less uniform. I rather like the effect quite a bit.

Thanks Ascension.

The closest I can find in gimp is the cubism filter.

Here is your example along with the settings I used (plus a contrast boost):
