Some of the works include the jingles which announce the stations in a variety of voice tones and languages, calligraphic massages on the sides of the tram stations and special lighting under bridges and between some of the buildings.
This is the artwork by Spanish artist , Jaume Plensa, called Conversation à Nice. It is installed n the centre of Nice at place Masséna.
During the day the sculptures are an opalescent white , but at night they are lit up and cycle through a range of colours.
According to Jaume Plensa's artist statement, the figures are meant to represent the 7 continents and the ease of modern communication. Additionally , they are meant be a modern landmark almost like a lighthouse and to watch over and protect the passers-by.
I have heard a variety of suggestions about the meaning of the statues that differs from the official one - the most common theme is that the statues are cross-legged Buddhas or possibly yogis who represent the different areas of Nice [quartiers] , although people are slightly puzzled as to why Buddhas represent the quartiers.
My favourite suggestion is from my kids and their friend is that the statues are giant jelly babies!
-though I suspect that is a very ex-pat British opinion due their familiarity with the jelly baby sweets.
