From Brad E Morgan:
Can $1 change the world? We're out to prove it can! Tipping Bucket taps the power of social media, micropayments, and money-back guarantees to launch social startups. Our project partners build community gardens in Baltimore, literacy centers in Bangladesh and maternity clinics in Bamako.
One project at a time goes into the bucket, with a funding goal and time limit. Users add drops to the bucketone click=one dollar. If the bucket tips before time runs out, pledged donations are collected and the project moves forward. If not, none of the transactions are processed and the next project gets its turn in the bucket. Basically; change the world, or your money back!
