Unity Vuforia AR #MixedRealities

This was my first time using Unity Vuforia. I find it hard to use without tutorial from Prasanth, but with the tutorial, making AR using 2D object becomes so much easier. I filed a few times trying to make it work before week 5's lecture. I eventually got it to work after looking at how Prasanth help other students. When it works, I realised the possibilities of Vuforia. The image we use to produce AR can be any thing. I first thing that came to my mind is what if the internet has a gigantic data base that stores image information in AR form.
