Thanks for the heads-up on ImageSynth and on the tutorials as well. The app is listed for $99
on their website. Is there any limitation on this free version? I'm anxious to try it on some textures from some of the many good free texture sites. I saw a nice review of it at creativemac
http://creativemac.digitalmedianet.com/articles/viewarticle.jsp?id=69057 and it looked like it was just the thing for making seamless high rez textures!
