Today, a pure coincidence to the announcement that Microsoft acquired Xamarin, my brother and I launched a preview into a project that we've been working on for some time now. This is a Xamarin.Forms UI Inspector called XenForms:

Also, in the spirit of giving. I have released an open source version of a game in Xamarin.Forms and CocosSharp. It's a These Crazy Walls Clone.

Hope someone finds it useful!
