The Nedbank Savvy Activation in Sandton City was a 12m tall billboard with a difference.

Fitted with state-of-the-art water technology, it allowed savings messages to literally rain down, thanks to a 4m row of water jets. A computer controlled the formation of the letters out of water droplets and then gravity did the rest. Visitors to the stand were invited to SMS their savings messages to the billboard and see them turn into rain.Messages poured in, as did the interest on social media.
