Scala Piano

Now that the 180 stairs up at Rotterdam's Central Station are taken down again, a new creation at stairs there has been introduced ~ Scala Piano or Climbing Keyboards or Stepdance Stairways... anyway the stairs have sensors  and stepping on them creates a note if not notes and that creating a sound of melody should invite us to using the stairway steps rather than the next rolling elevator!
Ofcourse I walked them steps down & up but didn't find my tune yet...
