I am happy to have this picture from a friend who recently stayed in Venice (grazie 
). It shows the work of the french artist Daniel Firman (born in 1966, he lives and works in Lyon) installed at the Bacini Vaporetto Stop opposite the Arsenale from 05.06.2009 to 22.11.2009.
It’s a 27 meter long installation saying Something Strange Happened Here.
Daniel Firman: “SSHH is a work that offers an extendable rendition of reality. The work provokes a questioning of one’s interpretation of the “world” in which we live. In this exhibit, SSHH submits itself to the extraordinary beauty of Venice, yet at the same time, to a vision even more complex and colossal such as that of our contemporary world. Without any explanation nor assertion, the work must simply remain a psychological or even a metaphysical question that one asks oneself.”
