Instant Cocoa from Soroush Khanlou is a framework made up of a collection of components and seems to take the Rails stance of convention over configuration with the aim to reduce the amount of boilerplate code we have to write. One of the components, Instant Router, certainly looks like it could simplify dealing with complex URL schemes.
AAWindow from Aaron Abentheuer has a clever way of detecting when the user is opening Control Center. I can see this being very useful for apps that use AirPlay, for example, as the user opens Control Center you could change the UI to show some useful information.
