This special space is a platform for exchange, where young people from different backgrounds and social status can come together to express themselves through their talents. The center is a rare place in eastern Congo where youth can come to escape the chaos of Goma’s busy streets, do something meaningful, and relax in an atmosphere that feels like an alternate reality compared to the grit that surrounds the concrete and barb-wired walls. Yole! provides free equipment to youth, including microphones, speakers, laptops, and video cameras and free training for film editing, music, and other arts.

Lenou Sypasurt is a young man who dreams of a literate youth population in Laos. With money he saved from working as a dishwasher in Australia, Lenou rented a small house near Luang Prabang, converted it into a library and classroom and invited the local youth to come – for free. Lenou grew up in a small rural village where the “local” school was far away and there was no library nearby. As an adult, he was determined to help the children in Luang Prabang have more opportunities than he had as a child. In 2009, he opened Lenou’s Library—a special place where children can borrow books, study, or take English classes.
