Free Seamless Textures From Spiral Graphics

I just saw this on Machinima.com, Spiral Graphics has released a new seamless texture pack with about 150 materials (they have two older packs available as well). You can get them from http://www.spiralgraphics.biz/packs/

The catch is that although the packs contain JPEG previews, the materials are in the GTX procedural texture format which I am not familiar with. I think this release is mainly to promote their Genetica texture editing software so I am not sure how useful they will be to Blender users.

How easy/hard is it to work with GTX files?

It’s a quite good soft which works with procedural texture nodes and even generates (mediocre) normal maps. If you are good at blendering you don’t need it. However, i wouldn’t say the money is wasted and woodworkshop is free. On the other hand it has lots of competitors like texturemaker or http://www.filterforge.com/filters/.

i need a specal software just to view the textures F*&% that
