The waterfall inside

Sanlam is one of the big life insurers in South Africa, and the holding company of South Africa's best short-term insurer, Santam, my employer. ;)

This wall of glass, to the left of Sanlam's reception area, has water pouring over it into a pool below... I'm not sure exactly what the reason is: perhaps it dampens voices and conversations in the reception area, perhaps it clears the air of pollutants, or perhaps it's just to create a talking point amongst visitors.
