For this years Festive Tech Calendar (23rd December), for a "bit of fun" I attempted to create an Augmented Reality Advent Calendar.
I initially thought I would place it on a detected surface, then I decided to use my head and go in a slightly different direction.. below is a video showing the result.
It isn't quite finished as you'll be able to tell. But it is.. unique and you get the idea.
If you want to learn a bit more about how to use C# and Xamarin to create iOS Augmented Reality experiences, you can check out my website XamarinArkit.com and my upcoming book on Amazon .NET Developer's Guide to Augmented Reality in iOS.
