Here is link to a website from Australia called Lent Event.
As part of this project participants are encouraged forgo an item from their daily lifestyle and donate the money saved so that others are able to live a life of dignity: clean water, nutritious food, elementary education, viable employment and essential healthcare.
There are some interesting videos and ideas on the site to think about for lent this year. http://www.lentevent.com/
