These puzzles were created by a non-profit group in Chennai, South India called Nalamdana, which means "Are you well?" in Tamil.
From the Nalamdana website, "We use innovative communication methods to provide knowledge about health to illiterate audiences. Response-driven participatory street theatre, interactive games and puzzles, audio and video cassettes, tele films, small group workshops, television serials. Nalamdana explores the full range of communicative possibilities to reach out to people."
