From right to left, top to bottom: Agate, Cloud, EasyWood, FireFilter, Fire, WormVein, Camo and ABFlagstone. The last is Electricity, blown up to show the artifacting.
Most of the textures look rather hideous, except for fire which I have gotten some good results from. The gridlines in the FilterFire example can be removed by using a series of parallel planes. I have a quick and dirty sample render using this method.
