I've been building a library of images that might be useful as building blocks for cool textures. You are very welcome to use them freely in your projects. All I ask is to be attributed as indicated on my homepage:
The images are on my "TXR" pages.
I'm adding new ones all the time, so be sure to check back often. I sincerely hope that some of them are useful. Any and all constructive feedback is welcome and always appreciated. :-)
All the best,
