Yeah, we are at WWDC at the moment wearing the t-shirts to promote the game and I have mostly been the back people have been playing off. It is a bit odd just standing there but I think people can have 'fun' by using it as a way to impress and shock people. The t-shirt draws a lot of attention and so it's great for people who like that kind of thing.

Also the game just needs the marker that is on the website and so it can be played off of laptops, iOS devices and even printed out.
