What an awesome concept!! gave me goosebumps!!
I have been thinking of doing something in the same lines with photography - I am from South Africa so I see poor people on a daily basis it makes me sad to see how unfair the monetary system is towards the uneducated and underprivileged - But it gives me hope to see concepts like this and to see how giving the majority of people on earth actually is - they just need to be lead in the right direction and giving should become as easy as purchasing an item from a vending machine ! Life is so busy and everyone just want to keep their own lives afloat so making it easier to give will definitely benefit charity organisations and their beneficiaries
