I've recently been talking to people in locations as far-flung as Finland and Australia about designing programs that support mindfulness and flow, so I suspect there'll be a very diverse set of submissions to the Happiness Apps Challenge:

The Happiness Apps Challenge is an international App building challenge that is aimed to inspire minds in tech and design to create products that will increase world’s happiness quotient!

Create an App to make people happy. One positive person can spread Happiness to more than 1,000 people, but through the power of technology we can reach out to millions.

You have until December 24 to enter. (Check out the some of the ideas for entries.) It'll be very interesting to see how this unfolds.
