 - [florent37](https://github.com/florent37) He is the creator of [ViewAnimator](https://github.com/florent37/ViewAnimator) which gave me the idea of this project. Some core concepts and ideas were reused, but everything is written from scratch.
 - [Android](https://android.com/) Some code is reused form the android source code and the VectorDrawableCompat support library.
+- [Alex Lockwood](https://github.com/alexjlockwood) The paths of the morphing sample is extracted from the [Shape Shifter](https://github.com/alexjlockwood/ShapeShifter) demo.
