Startup Idea : Birthdays dedicated to Charities/Needy

In this already materialistic world, we continue to nurture our children by throwing lavish birthday parties for them with friends/relatives gifting material gifts. I would like to create a website/iphone app/Android app where the friends/relative of the birthday boy/girl can dedicate meaningful social gifts(charities/child sponsorship/items created by the underprivileged communities/etc.). We can also have cute birthday cards printed from this website showing such a dedication. This will be a conscious effort from all the gifters and the gifted to build a service-oriented society! The best part is birthdays happen for people every day throughout the year!
