I recently came across an inspired little book called, Inspirability: 40 top designers speak out about what inspires. It includes some great pieces of advice from Chip Kidd, Milton Glaser and more. Funny how just hearing about how others get their inspiration can encourage and get ideas going. (And I gotta admit, I really like the green flocking on the book!)
To get your creative juices flowing, check out Coca-Cola Creator, where you can design a little Coke poster, of sorts. It's just the thing for a Friday.
