about the author
My name is Guy English. I write software for iPhone and Macintosh personal computers. For Tapulous I wrote the OpenGL engine, MIDI handling, Lua scripting bridge and content pipeline for their Tap Tap Revenge series of games. Previously I have worked for Rogue Amoeba on Radioshift for the Mac and Radioshift Touch for iPhone as well as some other products. Before entering the Mac development community I spent many years writing code for video games on various platforms for various companies.
