Have you ever won prices by shaking a tree? No? This could happen to you with the One Million Leaves (OML) app. The idea behind the app is that the leaves of the tree are ads with various cash prizes, gifts and discounts. If you check the ads, you get bonuses.
This extraordinay app concept is still in a demo stage, so it is meant to give a hint of the idea. Download the demo, shake the tree, and see how (currently fictitious) ads look like and how prizes are distributed. The initiators of OML consider the demo an important step towards the actual realization of the concept.
