Selection gallery tutorial

Hi everyone,
It's my first post in this section, but it has been a while since I started publishing Unity tutorials on my blog... and I'd like some feedback from the professionals now

Here's my last post:
http://brightreasongames.com/scroll-to-select-image-gallery/
It's a 5-part guide on how to implement a selection in an image gallery with snapping, inertia, zooming and sorting effects.

I've also made a few other things.
Here's a tutorial on how to map x-box controller input in webgl
