Yet another interesting link

This series of lesson plans looks at the relationship between art and mathematics in pattern design. With sections on traditional non-European art styles, such as Islamic patterns and Indian Mandalas, as well as famous artists for whom pattern was a key part of their style, such as Escher and Klimt. There's also a section on the history of the use of pattern in art, which goes right up from Prehistoric cave paintings right up to modern art, which is very interesting, and pretty relevant for me as I'm thinking of using Egyptian styles again.
