Most Demanding Art Project: Cryochrome
"Keep your shoes on. If you get dizzy, look at the ground." Those are quality pieces of advice in any context, but they were particularly useful if you were about to enter the piece of art officially called "Cryochrome" but popularly known as "The Rainbow Tunnel." People lined up for it all weekend having no idea what was inside (lollipops? vaccinations?): the answer, it turned out, was "a spinning interior that made it feel like all of Coachella had gone off its gravitational axis."
