Koeberg Road leads from the N1 national highway in the Table View direction, passing by the Caltex oil refinery, a dismal awful-smelling area. One of the few rays of sunshine while passing the billowing, smoking refinery is this few hundred meter stretch of wall that's been painted with a message. I couldn't find any details about who painted it or what it's about, but with words like "freedom", "virtue", "love", "caring", "joy", "happiness", etc. painted, I figured that the message was positive - perhaps with the intention of fostering goodwill and love.
