An anonymous reader alerts us to the IndieHIG Wiki, which is an independent effort to pick up the ball that Apple has dropped on human interface guidelines (can you spell FTFF?). From the wiki: "The IndieHIG project is an initiative created out of the necessity to document the new look and feel aspects of the Mac OS X experience, outside of the supervision of Apple itself. The project is not intended to replace, but rather to supplement the somewhat dated Apple Human Interface Guidelines (HIG). There are many instances of Apple using new and experimental interface styles, spurring developers to emulate these styles in their own applications. Unfortunately, because Apple provides neither guidelines nor code for developers to work with, the implementation of these interface styles and features by third parties can be lopsided and directionless. The IndieHIG intends to change this by providing a comprehensive set of guidelines governing the use and appearance of new, undocumented interface elements so that their implementation by third party developers adheres to the unwritten standards that Apple has set."
