Theres a line in the Micato brochure about clouds on the Serengeti that pile up in grandly crazy towers, looking like computer-generated special effects. A colleague took mild issue with the last part of that description—the special effects part. Too jarring, she said. It takes you away from the actual world.There may be some truth in that. But so digital is our world—and so photoshopped our photographs—that we sometimes fleetingly wonder if what were seeing is actual, or whipped up for our benefit by some unseen Oz with a whizbang computer.
