Unlike other camera apps this does one thing -
Create crazy recursive photos.
Its easy to use, incredibly fun and has 2 main function which interact with each other
First one allows you to pan,rotate, zoom the selected image. You can also use the brush mode to reveal parts of the selected image.
Second lets you switch you between the back and front images.
If anything goes wrong just press the undo button.
Sounds easy, give it a try.
I might add a gif feature in the next release if people like this one
