Walk across Safra Square, the Jerusalem Municipality complex, and be surprised!
The pillow sign said "Touch me" so right away I touched it, only to discover, rather sheepishly, that it was hard as rock.
Only then did I see the rest of it:
Concrete cushion installation -- Smadar Carmeli
Around the corner there were more.
A whole plaza of deceptive cushions!
Here is a little video of the installation being set up and enjoyed.
Even Mayor Barkat tries out a cushion.
