I've been developing user interfaces and application software out of San Jose, California in the San Francisco Bay Area for nearly 20 years. For the past several years I've worked on mobile applications for iPhone, iPad, and Android devices.

The code and demos for the book are provided in a gzipped tar file. See the readme file included with the package to run the demos after extracting.
