I can’t find any pictures for this one so I’ll just have to describe it. It was made with the same black string you see in the second string piece. It was simply one long piece of string hung from metal beams on the top of a three story stairwell (like the one in fit to be tied.)
It dropped all the way down to just a couple feet above the floor and swayed back and forth with the slightest breeze. It was basically a three story art work hiding in plain site! For those that happened to see it I hope it was a pleasant surprise.
