Early MacPaint and Quickdraw source code is worth a look. Clean and simple, yet solved a rather complex problem. http://www.computerhistory.org/atchm/macpaint-and-quickdraw-source-code/ http://www.computerhistory.org/atchm/macpaint-and-quickdraw-... Here is what the author said about it (and code in general): "It’s an art form, like any other art form… I would spend time rewriting whole sections of code to make them more cleanly organized, more clear. I’m a firm believer that the best way to prevent bugs is to make it so that you can read through the code and understand exactly what it’s doing"
