Speaking of what's usual with OpenSource development, I am wondering if you had been working together with André Schneider https://github.com/schneiderandre on this project? As I saw the Demo I saw the similarity of some effects, they look like they were taken from André's Popping Library (https://github.com/schneiderandre/popping).
You mention him as a developer in the sources, that's good:
But it's copyrighted now to Meng To? That's why I ask..

As far as I can see he licenses his sources under MIT license, probably best to include it for those externals. If you'd been working on this together, just ignore this post :)
