When visual elements are seen moving in the same direction at the same rate ( optical flow ), perception associates the movement as part of the same stimulus. For example, birds may be distinguished from their background as a single flock because they are moving in the same direction and at the same velocity, even when each bird is seen—from a distance—as little more than a dot. The moving 'dots' appear to be part of a unified whole. Similarly, two flocks of birds can cross each other in a viewer's visual field, but they will nonetheless continue to be experienced as separate flocks because each bird has a direction common to its flock.

having spent my fair share of time in the data center, I can understand your sentiment. However, with vBlocks, I don't see any black box or curtain–more like a screen door. We have been up front about components, specs, mgmt capability, etc. I think, at the end of the day, folks will consider the reduction in hassle/cost against the reduction in control. Sometimes it will make sense and sometimes it won't. I think most folks will do this on an app by app basis and the typical data center will be a mix of vBlocks, unified computing, and conventional customer-integrated infrastructure.
These principles of organization play a role in perception, but it is also important to remember that these principles can sometimes lead to incorrect perceptions of the world. For example, imagine that you are out hiking in the woods one afternoon when you spot what appears to be a moose behind a large tree. You immediately begin to leave the area to ensure you don't disturb the animal, but as you are hiking around you realize that the "moose" behind the tree is actually just two large broken tree stumps. Because of the Gestalt law of continuity, you perceived the two disconnected shapes as one continuous object, which your brain then interpreted as a moose.
