This book proposal (used with permission, approval is still pending) was a clever concept relayed to me by a friend, and we really wanted to see if we could make it happen. The idea of kids of different nationalities saying HI in their native languages is very appealing.
Research was necessary to find the greeting in four different languages plus typefaces and spelling in those languages. We also needed to get the pronunciation nailed down so the kids would be able to say it in the native language.
The design is aimed at younger children as that is the best time to make them aware of the various cultures in their environment. The book would help them understand that people are interesting and diverse but very much the same despite some of our outward differences.
