Very quickly and simply change your photo to an illustration. My favorite use has been to illustrate my life as a comic book. I then use other apps to finish the process. But there are other uses way beyond this. Lots of choices including video. Works from your library or the camera. Take a look at your world from a new perspective.
I just want to add here that even after years of using this I still find it inspires new creative ideas in me.
A year later... Still good.
