Michael Daley is cofounder of 71Squared.com and author of Learning iOS Game Programming. 71Squared.com is an indie development shop that produces OS X-based tools for game developers, namely Particle Designer and Glyph Designer. Mike also produces video tutorials through the 71Squared.com blog, which cover the basics of game engine design using a relaxed, easy-to-follow approach. Mike is a strong believer in delivering resources that help new entrants into game programming get up and running by breaking things down and introducing simple approaches first. This allows people to see results and not get too bogged down before they even get started. In what time he has left, he flies light aircraft, plays games, and tries to introduce his children into the world of all things Apple.
