Brown

It is pretty and refreshing, and especially as the buildings around are modern and very sober anyway it is just well fitting as an element that divides the square so the emissions of the road are not noticable that much from the large outdoor cafe sitting below the seniorcitizen residence.
I wonder what happens when people discover that a group of funny sculptures and a trickle here and there are a less good durst and motor sound binding barrier than huge dandelions of water droplets.
