Half the fun of an actual rainstorm is that the deluge is unpredictable, a natural outburst whose duration is unknown and whose force fluctuates according to invisible conditions like wind and temperature. The "calm before the storm before the calm" injects a dimension of abstract narrative.
It tends to be messy and unruly.
In "Rain Room," the immersive installation at the Los Angeles County Museum of Art that simulates a heavy downpour, the messiness is all cleaned up — smoothed out, unruffled and neatly organized for your 15 minutes of viewing pleasure. It's a Minimalist storm. "Rain Room" performs plastic surgery on nature.
After high-profile stints in London, New York and Shanghai, the installation opened Sunday and runs for three months. The rain shower paradoxically happens indoors, inside a black-box room.
Even more unexpectedly, it keeps people who brave the storm nearly bone-dry as they venture forth into the falling rain.
The special effect, created by the London design company Random International, functions through a computerized system of 3-D tracking cameras, which are placed at intervals around the ceiling. A grid of overhead nozzles lets fat drops of liquid fall to the floor in steady streams, passing through a field of injection molded tiles.
When the cameras pick up a person's body entering the field, they signal the nozzles directly above it to close. A column of dry air with a roughly 6-foot radius moves with you as you walk slowly through the room.
Let's stipulate at the outset that "Rain Room" will be a popular hit. Brainless amusement often is.
This one's got everything, starting with the cinematic "Oh, wow" factor that drives all special effects, whether for the superheroes of "The Avengers" or the high-wire protagonist of "The Walk." Like them, "Rain Room" is photogenic.
It's even selfie-ready, thanks especially to a single bright, white theatrical spotlight that illuminates the falling water from the side. The rain is turned into Swarovski-worthy sparkles of glistening silver.
Video — ideal for broadcast television and eye-catching online media — can further inflate the dramatic action. It frames shadowy, backlighted figures mysteriously moving through glistening space. (You've seen pretty much the same shot in a hundred movies, from "A Midsummer Night's Dream" or "Casablanca" to "In Cold Blood" or "The Terminator"; now, you get to star.) Videos pump up the publicity factor in ways that few paintings or sculptures ever could.
And "Rain Room" is exclusive, like a chic nightclub in Hollywood or a reservation-packed restaurant. Anyone can buy a ticket (a $10 or $15 upgrade to a general admission ticket or a Frank Gehry ticket) for 15 minutes inside, although getting that ticket can be tough.
Exclusivity is often a powerful draw. This is appointment art, and appointments book up.
The number of daily visitors must be carefully controlled. Any more than seven people inside at one time, and "Rain Room" can begin to experience technical difficulties — even to the point of overloaded surveillance cameras signaling to shut down everything.
But looking at glamorous pictures is far more appealing than actually being inside, which turns out to be rather banal. What's this immersive installation like inside? The experience is not so different from being outside looking in.
Watching a downpour is all there is. Standing on the room's periphery offers a contemplative experience hardly distinct from being inside the storm. Heightened physical consciousness comes only when you get wet.
Sort of the way it does anytime it really rains. And you will get wet, at least a bit, from errant drops suddenly splashing on your head or sleeve.
This is technology, after all. Just like when your smartphone decides to freeze up or your Wi-Fi unexpectedly drops, the electronic on-off switch controlling the room's rain can't necessarily catch every bit of water seeking its own level. Like Windows 8 or Apple's Lion operating systems, there will be bugs.
A complex computer system hidden offstage controls the action out front. It might be better if they let it all hang out.
The show is presented as the first in LACMA's Art + Technology partnership, funded by Hyundai Motor Co. and announced in March. It comes with no particular museum curator attached — the first such LACMA exhibition I can recall. That no curator is willing to claim it should give one pause concerning the new project's direction.
"Rain Room" seems a pale and (you should pardon the expression) watered-down riff on "The Weather Project," the famous illusion of an enormous, glowing indoor sun with which the compelling Danish-Icelandic artist Olafur Eliasson drew huge crowds to the Turbine Hall of London's Tate Modern a dozen years ago. That was a couple of years before the London-based Random International team got together.
"Rain Room" is Weather Project 2.0. In design, a related loss of product quality comes when a focus on production shifts to a focus on audience consumption. Except for being a mildly entertaining spectacle, not much of any interest is going on in this bland tempest.
