Eliasson’s optical machines and installations – such as Kaleidoscope (2001), New Berlin Sphere (2009), Your welcome reflected (2003), and Seu planeta compartilhado (“Your shared planet”), (2011) – reflect the artist’s ongoing investigations of color, perception, transformation, and deconstruction, an inquiry that is particularly interesting in relation to the baroque context.

A site-specific intervention in the form of a continuous mirror traversing the enfilade of grand rooms further disorients the viewer by folding and re-folding the complex spaces it produces. Wishes versus wonders (2015), a steel half-ring mounted to the mirror wall in the Hall of Battle Paintings, stages an encounter between reality, illusion, and the elaborate artifice of the surroundings, simultaneously multiplying lines of potentiality.
