I had a toy sheep like that as a kid, so it seems like a legitimate app to me, sorry to hear it was rejected. I noticed those fake fingerprint scanners -- at least two of which were consistently in the top 100 -- last year when I was creating an app that performs real 3D scanning. I thought "Surely if a fake fingerprint scanner is so popular, something that actually takes a 3D scan of your face would be even more popular." I was incorrect. (Though my app has done just fine -- it's just that those fake fingerprint scanners are disgustingly successful given what they are.)
I just bought your app out of curiosity. That is a very interesting concept -- would love to see how you keep innovating further! Good luck! It took a few tries/a darker room to get just the right effect. I don't actually know much about image processing -- I figured you would try to detect the face/cheeks/nose and "extrude" those when rotated, but it seems like it's doing something more sophisticated.
