Related to #BoneConduction: One of the most moving art pieces and concepts I know of is (was?) the "Touched Echo" installation by Markus Kison in the center of Dresden, allowing visitors to "hear" the sounds of the British carpet-bombing air raid from February 13, 1945, when they rest their elbows on the railing near the river and hold their ears closed... Nothing is heard/felt by any bystanders nearby... Such a powerful concept and window to the past!
