Useful Book!
A developer I work with brought in a new book that he thought I might like. It's Robin Williams Design Workshop and it's pretty good! While it does advertise her earlier books and refers to them as resource material constantly, there are some good ideas about design and lots of visuals to get your creativity hopping. There are sections on working with clip art, creating visual impact, and then a whole bunch of stuff on creating projects from logos and invoices to billboards and Web sites. It's a bit pricey ($60!), but if you can't afford to buy it, pick it up at a bookstore and just browse through it for fun and get a few design tips.
