Updates from Derren Brown and the Enigma Crew

For nearly two decades, artist Rafael Lozano-Hemmer has planted motion detectors, searchlights and surveillance equipment in public plazas and parks around the world. Each time, he invites the public to activate his gadgetry with their shadows, heartbeats or some other form of interaction.
This fall, the Montreal-based artist plans to turn people’s voices into colors. On Sept. 16, the Solomon R. Guggenheim Museum in New York will unveil “Levels of Nothingness,” his interactive installation that will allow people to speak into a microphone connected to a computer that can match their voices’ traits, such as pitch and tone, to certain colors. A network of roving spotlights around the museum’s theater will instantly send the corresponding hues shooting around the room like at a rock concert. Actress Isabella Rossellini has already signed up to speak first, according to her spokeswoman.

Mr. Lozano-Hemmer, 41, represented Mexico in the Venice Biennial two years ago, and his collectors include New York real-estate magnate Jerry Speyer, Mexican beverage king Eugenio López Alonso and Miami entrepreneur Ella Cisneros. The Museum of Modern Art in New York and the Tate Modern in London also own his work, which can range in price from $90,000 to over $700,000, according to his dealer.
