Photo Unfolder makes a series of collages from your photograph. It uses a simple algorithm to make each collage, but the repeated, recursive, application of that algorithm results in unexpected complexity and compelling images. The default mode is fully automatic and displays each collage in turn as it is created. Additional modes can be activated from the Settings page. One mode allows you to choose what part of the current image will be used to make the next one. This allows you to guide the creation of collages to preserve the parts of the image you like. This can be absorbing and rewarding.

The challenge will be in learning what sort of image results in the best collage. Photos with linear elements work better than those with subtle gradations of color. Architecture, signage and typography can be interesting, for example.

Images created with Photo Unfolder can be saved or shared using the Action button on the far right of the toolbar at the bottom of the main page. These images can be as large as 5000 pixels square. Meaning they are suitable for printing quite large. Results will vary depending on the number of iterations because each application of the algorithm includes a rotation of the photo. This introduces a slight blurring each time. Images made with many iterations will look better printed smaller to minimize the blur. Most images created will be suitable for sharing to the web which can be done through the Action button.

Addictive Artistry

This app is the best thing on my phone at the moment. It is one of those things that you may never master but will meet so many happy accidents along the way that you will feel artistically accomplished. You chop up photos and make patterns, weird juxtapositions and angle combos that are just unthinkable up to the monet that you click here and create them. I send "Unfoldered" images of pics of friends of mine to them and they immediately want to know how i did it. Should I tell them? I want to keep it a secret and be the only UNFOLDER in my circle because once the word is out everyone will be making patterns and puzzled combos with this thing.


Great little algorithm

This app takes a great algorithm for creating fractal art out of ordinary pictures and presents a smooth, user-friendly UI for using it. Alrhough it is more of a one-trick pony, that is what apps should be. The way of Unix :))


Finally, a window into a cursed reality

I took a picture of my phone in a mirror and ran it through this until it looked like a Studio Ghibli movie. Worth the $1 just for the goof off potential.
