During a walk today cut short prematurely by the rain I came across these reflective spheres which are attached to a wall along a gated alley just off the Skutsjespad, across the ING head office. Does anyone know what they are there for? My guess is it’s some sort of art installation so that the people in the office building to the right have something more interesting to stare at than a blank wall. (You can see the ING House in the reflection of the left most ball.)

Yes, dear lazyweb, I did Google for the answer, but my search for skutsjespad balls “did not match any documents.” Anyway, it’s nicer to guess.
