In 2002, Yeh traveled to Accra, Ghana, to collaborate with her host Heidi Owu, a dedicated educator in the International School in Accra, and community leaders to carry out a land transformation project.

The project took place in an impoverished neighborhood in Jamestown, located in the old section of the city. The undertaking engaged hundreds of children and adults in transforming a bleak courtyard into a public space full of patterns and colors. The project encouraged people's creativity and action; it made people feel hopeful and empowered.
