This Wall Street Journal video shows a Japanese vending machine that uses a camera to identify (guess?) your gender and age. Based on that data, and the weather, it recommends a particular drink to you. Interestingly, this report also presents banana vending machines as innovative. (Yeah, yeah, just look at it, etc.) But I've seen fruit vending machines around the US for years.
