I love this Japanese augmented reality game for the iPhone. Gamers can capture virtual butterfly’s using their phone, and the type of butterfly’s available is based on your location. So the more you travel, the bigger your collection!
I imagine companies could invest in creating special limited edition butterfly’s, helping bring people to their stores.
This is a typically Japanese game – they love collection based games (think Pokemon). But it is certainly something I could see catching on over here.
