## What it is
A UICollectionViewLayout subclass for iOS that displays items of different sizes in a grid without wasting visual space, using a balanced photo gallery algorithm. It is written in Objective-C and distributed via CocoaPods.

## Use cases
- display photos of different sizes in a balanced grid on iOS
- create a masonry-style photo gallery in a UICollectionView
- avoid wasted space when laying out variable-sized items
- build a perfectly balanced image gallery layout
- show mixed-size thumbnails in a grid without gaps

## When to choose
- you need a space-efficient, balanced grid layout for variable-sized items in an iOS UICollectionView
- you are building a photo gallery on iOS 6/7 with Objective-C

## When to avoid
- you need a maintained library - this project is explicitly no longer maintained
- you are targeting modern iOS with Swift or SwiftUI
- you need layouts beyond balanced photo-grid arrangements
