“The installations are in places, parks, cities, and areas not often visited by either tourists or residents. “ Desert X is a big, wonderful treasure hunt,” Davis says. Davis, the project’s founder and the editorial director for The Annenberg Retreat at Sunnylands. Half of the fun of Desert X is actually finding the artwork, says Susan L. From a house built out of mirrors to an optical-illusion wall, the pieces, set against the stark contrast of the Coachella Valley landscape, are striking. The free exhibit, which spans the Greater Palm Springs area, started during Palm Springs’ annual Modernism Week in February and extends to April 30 through the Coachella Valley Music and Arts Festival and the Stagecoach Festival in Indio. You don’t have to be a design or an architecture aficionado to appreciate Desert X, a 16-piece collection of visual artwork housed in a unique gallery-California’s desert.
