Dispersion(Pixel) Effect Photo Edit is a free and powerful application for your iPhone. It gives you the ability to make your photos look like pixels.

The effects can be applied using filters such as black, white, color, and even the color wheel. You can apply the effect to just a few photos, but you can also apply it to an entire batch of photos. It will apply the effects to your pictures using the pixel grid you've selected, and it will adjust how many pixels the effect spans. You can select the pixel areas manually by tapping on the screen or letting it choose the areas for you.
