Dan Acher, artivist

Dan Acher is an Ashoka Fellow and the founder of Happy City Lab. Central to his work is art as generator of social change across local and global communities.

Dan uses cities as playgrounds in which citizens of all backgrounds can connect and engage with the key issues of our time. His large-scale installations and new ‘city rituals’ create meaningful bridges across social, cultural or political differences, allowing strangers to come together beyond what may divide them.
