I'm honestly not sure how to summarize this video. It's a very interesting look at the way that the impulse to "optimize" gameplay affects the culture surrounding games, especially MMOs and other multiplayer games. It particularly looks at World of Warcraft and the social norms that have developed around and within the game. It's a long watch but I found it really interesting, and I have zero connection to WoW and have never played it.
Mojo Lens seems to have created a "smart contact lens" with a pretty dense display along with a fair number of other features including a wireless radio, accelerometer, gyro, and magnetometer (for eye tracking). It all seems to fit into an incredibly small package which is apparently thicker than normal contact lenses, but still wearable as demonstrated by their CEO. It seems like a pretty exciting piece of tech. I have suspicions that the battery life is probably the most limiting factor but I'm going to be following this with interest.
