Dover Publications has two books on origami with dollar bills, and they look like they would be a lot of fun. The first, Dollar Bill Origami (ISBN 0486429822), has 37 different projects from beginner to advanced, and include a butterfly, boat, windmill, and peacock. The other is Dollar Bill Animals in Origami, (ISBN 0486411575), with 30 animal projects.
