Our new Unity book is available, in rough early release form. Buy it now and get all the updates! It's also on sale (code: CYBER15) for Cyber Monday (whatever that is...) The details are over on Paris' blog.
We build amazing iPhone and iPad apps. We recently built ABC Play School Play Time and Art Maker for iPad, and recently wrote Learning Cocoa with Objective-C Fourth Edition and the iOS Game Development Cookbook for O'Reilly. This is our blog.
