Rachel Tiep-Daniels and Margaret Wuller have been working on wrangling up line and colored art from a number of talented artists for a coloring book that will benefit orphaned children in Ghana, Africa and Tijuana, Mexico. The submissions look like a whole lot of fun. Copies of the coloring books will be given to the children with proceeds of sales being donated to the Corazon de Vida Foundation.

Their blog has many (if not all) of the submissions for the book and general updates on it's progress. There's a facebook page you can join to follow it's progress as well.
