The boundary between the physical world and internet is narrowing. There is a lab in a quiet corner of Stellenbosch University where a group of post graduate students are doing quite extraordinary things. The vibe in the lab is relaxed and convivial. An aroma of freshly brewed coffee lingers. It’s almost cosy. Yet it’s obvious that this is no ordinary laboratory. The banks of computer screens are one give-away, the carpeted floor – no linoleum here – is another, and the working relationship with media giant Naspers MIH is another.
