Dover graphics books had some excellent stuff for that most of mine came from old bookshops and garage sales, search dover books on Yahoo! or Google they are still in business. Dover stuff was essential in the graphic fields before computers, they still print but many of their books now include a CD rom as well and I use a few of these in another field. Otherwise you can create your own with a drawing program, Coreldraw 9 has an extensive range of geometrics in the fill libraries and can export and save as a jpg. Then too remember your photo program will have a turn to B+W command. There are a lot of free and share software for graphics at ZDnet and Cnet worth a look can remember a few fractal creators, I've been playing with Repligator 6 and posted a link here, not exactly what you are looking for but may be interesting and of some use. Anything specific you can email me for further info. Tommy.
