Sean Shim-Boyle lowered the rafters in LAXART's side gallery, so if you're more than 6 feet tall, you might have to duck a bit to avoid hitting your head on raw wood beams. At the back of the gallery, two staggered sliding doors with similar raw wood frames keep almost closing, then sliding open again. Shim-Boyle placed the sensors that dictate the doors' movement too close together, so they are locked in a battle with one another. You feel the tension as you walk in, around and between them. And because of the room's wood-heavy feel, it's as if technology and nature are on a collision course but keep missing each other and backing up to try to hit again. 2640 S. La Cienega Blvd., Culver City; through Dec. 21. (323) 868-5893, laxart.org.
