Hi there,
here is my first project in openFrameworks. It is not technically the first thing I did in openFrameworks, but I consider it the first project where I used concepts I’ve learned by trying to study it, like meshes, textures, etc. I had never done 3D animation in Processing, because it was too slow, so I didn’t even thing my crappy laptop was able to handle it, but it seems it does. I’m really impressed! 
Here you find a blog post where you can download the source code.
Thanks for developing and mantaining this amazing toolkit!
Best,
Alessandro
