The document discusses creating photo collages in iOS apps by using a blocked recursive image composition method to arrange photos on a rectangular canvas. It references existing JavaScript and Objective-C libraries for creating galleries and collages and proposes developing the collage creation into a publishable library with support for iOS and Android. General dimensions for the canvas and tests using ScalaCheck, Functional Swift, and random test sets are also mentioned.
