A few months ago I mentioned an interesting example of a scrolling view with a dynamic variable blurring effect inspired by the Yahoo Weather app.

Here’s an interesting project from Justin M. Fischer called Core Background.

Core Background is inspired by the Yahoo Weather app and provides a number of utility methods for grabbing details about a users location, gathering images based on that location from Flickr, displaying images from a set of stock images, and applying a variable blur effect with everything running outside the main run loop and caching built in.

Here’s a video showing Core-Background in action:

You can find Core-Background on Github here.
