The basic idea of the application is that you can formulate a wish and share it with people around you. The wish takes the form of a seed that you need to cultivate by giving enough water and light. Little by little the wish grows into a tree and it starts making flowers. People nearby can see your wish because it is planted at a geolocated position and can send you comments and encouraging messages to help you make you wish come true.
The concept of the app came out of the joint work that we did last summer with the UDSI team in Barcelona. I also like the idea because of my past work with the DigitalSeed [link] etc.
