You guys should make a web page.. seriously. Write something up about why tubing existing artworks without permission is wrong, and offer other avenues for people who love tubes to pursue.. instructions for making your own work to tube, for instance, or links to places where you can tube to your heart's content. There are tons of royalty free sites out there. Maybe even offer some free tubes of the sorts that people like (fairys, etc). The people who tube with abandon won't care, but I bet that some of the tube collectors are clueless about the copyright issues involving tubes and wouldn't mind the education. The idea of tubes is not a bad one.. I use DigArts image hoses for postwork, for instance. Some education is needed. Also, you guys might want to check out the creative commons.. it's a new method for copyrighting your work so that mere mortals can understand it.
