Storybird.com is a fantastic website where writers can play with story lines without having to worry about the illustrations! Talented artists upload their professional work for writers to choose from. Using a simple drag and drop system, authors choose illustrations and write to the pictures. Teachers (like myself) can subscribe to their service and create student accounts (which I have) which the students LOVE (and trust me, they do).
I was clicking around on their blog and saw an awesome post about the original ideas for the site and how the logo was created. I love seeing inspiration boards and original sketchings. Bravo storybird!
