Video explaining the AR or VR..

I actually downloaded this app and its pretty fun to use, I do not own a google cardboard (the part that is necessary for the VR- only 15$) but I can use it with the VR disabled on my smartphone for free (true for any android or IOS device). Its pretty awesome, a neat game with some awesome applications for teaching. 
I could see myself doing a lesson on this in a biology classroom when talking about cells viruses or even optics because of how we see VR. 
I really liked this app becasue i think it would be a cheap and easy way to get students involved and interested and excited about learning by relating it to a game.
