Body Chimes

From the installation plaque:
Presence 2007
The installation’s “platoon formation” is in reference to Fort Bonifacio’s history as a military facility transformed into what we now know as Bonifacio Global City….. The subtle sounds are intended to generate good vibes resonating through the park.
Push gently on the middle part of the pipes to activate the chimes.
I went nuts pushing them all in turn. But in a martial arts movie in my head I was able to move six of them at once!
