External Interior

"External Interior" is an inside-out disco ball made with 1600 one-way mirrors of the type of found in police station interrogation rooms. The mirrors are mounted on a transparent acrylic sphere that is suspended from pulleys and has a counterweight so that it can be raised and lowered easily. The sphere is illuminated with an external spotlight and can rotate freely, like all disco spheres it produces a projected array of points of light. As visitors introduce their head inside the sphere, they see a mise en abyme reflection multiplied kaleidoscopically, creating both a spacious, yet isolated, self-centered experience. The effect is reminiscent of both Julio Le Parc’s mirrored sculptures and the tessellated vision present in insects with compound eyes. Meanwhile, from the outside, the public can clearly see the person inside the sphere.

A companion piece called "Internal Exterior" will be identical except that the one-way mirrors will be flipped: when a participant is inside he or she will be able to see everybody while the people outside will not be able to see him or her.
