Tarja responded to my request for a simple logo with "Sure. I'll be all day in Mänttä but as soon as I come back." In the morning in a DropBox folder was the logo in various versions.
Tarja is a great illustrator and book designer. She has designed so many children's school books in Finland and her illustrations are wonderful. At the moment she is working with Adobe on a project where her illustrations are being animated.
