I wrote few days before the wiki page: http://wiki.openstreetmap.org/wiki/Texture_Library.
Now I have participants from 3 countries: Germany, Poland and Russia and lot to do.
If everything works well, we have im Summer very nice texture library.
I´m not sure: Is wiki the best address for such collection of textures?
If not, what to do?
How to arrive participants in other countries? There are lot of country specific textures.
You can see results of textured surfaces under JOSM PlugIn: Kendzi3D.
I would be happy to see someting like this under Potlatch.
