PowerSketch is a US$0.99 app from the developers of PowerCam that takes any image and applies a variety of filters to turn the image into what looks like comic book art, a pencil drawing, and effects like rice paper, neon and more. The app supports live preview and can operate your iPhone camera, or you can pull something from your camera roll.
Finished photos can be sent via email, Facebook or Instagram directly from the app. I found the app does what it advertises, and there are plenty of choices. You can even create collages. Like all filter type apps, you can overdo it, but this would be a nice app to take a holiday photo and turn it
