Now this is a interesting one. Would be good down the Hoe, only of a different sort of war memorial.
It is a invisible war memorial which 'sends the user back in time' to 1945 as B-25 bombers, destroyed most parts of Dresden's Old Town in WWII and this locational they can see on the other side of the river Elbe. This bombing happened on the 13.2.1945.
This intervention is activated by bone conduction: In their role as a performer they put themselves into the place of the people who shut their ears away from the noise of the explosions. While leaning on the balustrade the sound of airplanes and explosions is transmitted from the swinging balustrade through their arm directly into into the inner ear (bone conduction).
