In response to a contest organized by consulting firm  PSFK and the Climate Reality Project, designers at Stark Design have proposed an interactive concept that would create a giant Tamagotchi game for the city of New York (and be adaptable to other cities). From the designer’s description:

“REALiTREE is a digital representation of our local environment and the role we’re playing in sustaining its well-being. It is a game played by different groups in many places. Individuals, teams, communities, cities and even countries compete against their counterparts via Twitter, Facebook and through other digital social tools.

A REALiTREE is like a huge Tamagotchi which thousands of people care for. And that’s not all.

It is a massive projection, run using renewable energy, showing a digital image of a tree, complete with leaves, branches, roots, sky and earth. REALiTREE functions like a real tree, in that it will thrive and suffer according to the health of its surrounding environment.”
