So, in exploring online I found out about the app Ingress from this post! (11 Google apps you probably didn't know existed) & I want to play it; so bad! Here is a picture from the post, thank you Venture Beat for mentioning it!
I am hoping I can start playing around with it in the next couple days. I can see this being used in my classroom, no doubt. Having classroom competitions, using Google Maps with it, etc. Check it out for me & enjoy the game, since I can't in lil 'le SouthEast Iowa :(
