There’s a lot of cool apps in the Apple App store (try saying that 3x’s fast) that’ll bash up and distort a picture until it turns into something that barely resembles the original. I’ve had a lot of fun playing with some of them and have actually ended up with some assets that I’ve used in some professional projects.
This one is called Fragment and it easily produces some nice effects that would take a bit in Photoshop. This one reminded me of a Journey album cover.
If you’re interested, you can find Fragment right about here.
