I'm glad you like it! I did work on themes back in the day, at the very end before OS X came out. I was only in high school though. I made several themes, but I didn't have the ability to make a program that accesses resource forks and shifts around bits and bytes the way this one does. I didn't even understand pxm# color tables so all of my old themes are 24-bit color -- way slower and larger file size than they need to be. I mitigated that with the use of color table ppats when possible, but those are only useful for non-transparent images.
