“The Geometry of Conscience” is a powerful memorial installation in Santiago, Chile created by New Yorker Alfredo Jaar to honor Chilean victims of Pinochet’s dictatorship. In a detour from many historical monuments, Jaar chose to construct a uniquely impactful experience for visitors, to help them connect with and understand their collective memory. Housed underground, only 10 people can enter at a time. Once inside, they experience one minute of full darkness, followed by the back wall slowly lighting up hundreds of silhouettes, growing from 0 to 100% in intensity over 90 seconds. Another 30 seconds of darkness follows, creating a strong after-image effect.
