Flow was commissioned in 2005 to research and write the scientific text and exhibits for the Sterkfontein and Maropeng visitors’ centres in the Cradle of Humankind World Heritage Site. This included developing storylines covering topics like human evolution by consulting with paleoanthropology experts. The R350-million project was officially opened by the President and has been very popular, attracting tens of thousands of visitors. Flow was also tasked with writing scripts for audio-visual elements at both centres and producing an educational resource pack for the Cradle of Humankind that was endorsed by education officials.
