A name, a concept: Snowball
The name Snowball lends itself to great graphics, like that winter Sunday comic staple of the snowball that starts tiny at the top of the hill and becomes huge at the bottom— or better, a dozen kids pushing a six foot snowball.
And the first level of a project funding could be: "Snowball's chance in hell." If you double your funding goal, you get Avalanche.
Giving Snowball.VisionsUnite.org the tagline: "Helping snowballs make it through hell since 2011."
