OOK, Once I Owned a Kestrel, is now being revamped. Previously, it was to be released solely on iPhone and iPad. Now, iPhone, iPad, and other mobile devices are dropped and it will be primarily a desktop project. Welcome to the new OOK. Enjoy.
Version 1.1 of Universal Layout, compatible with OOK v0.01 (Physics Demo) and OS X 10.5+
