I'm with Nynx on this one.
If you look closely there's a texture being used because the very top one is one I would see on a rock.
I'm sure you'll find the right texture to use though c:

Hopefully the pyramid mesh/texture is in there.
If not I would message the owner here (http://thelaserbeam.deviantart.com)
To see if they can send you their mesh. :)
