Out for a walk near the banks of the Yarkon River in Tel Aviv

This is a wall in the coffee shop area. A video is projected onto the wall, a piece of artwork in itself called Cypresses. It shows people moving up and down, almost trudging on hills in the blue spaces. Hynotic effect.

As the sunlight changes so do the shadows cast on the wall from the skylight. See the next photo, taken only a few minutes later, with hardly any shadows when the sun went behind a cloud.
