I've been looking up some books in the libary, and I found this one called the art & culture of Bali. It looks really helpful, and I've scanned some of the images from it. It's also got some diagrams of patterns, but I need to read some of the book to get some background infomation on them. They seem to have a particular purpose, so I'll make a separate post once I know more about them.
For now, here is some of the pictures from the book.
