                                hide in shadows and run on walls &#150; when they can 
                                sit out in plain sight in a well lit room and 
                                just wait for you to walk by so they can jump 
                                on you from behind &#133; scares the sweat outta 
                                ya. You hear stories about someone getting on 
                                an elevator alone, closing the door, hitting the 
                                button, and just as it starts to move they hear 
                                this god-awful chuckle ...&quot;</p>
                              <p><b>Thesis:</b> the outermost epidermal layer 
                                becomes a crude computer screen, using skin pores 
                                as pixels, and secreting pigment for color. When 
                                the alien stops moving, it probably &quot;plugs 
                                in&quot; to the local bacterial network, and &quot;downloads&quot; 
                                the correct background image. As this evolution 
                                becomes more efficient, the &quot;pixel&quot; 
                                count increases. Kharaa are naturally resistant 
                                to most forms of detection &#150; for instance, their 
                                body temperature tends to match the room's. With 
                                the cloaking evolution, their ability to disappear 
                                is total. This upgrade works only when stationary 
                                &#150; once the alien moves, or attacks, the link is 
                                broken, and their skin reverts.<br>
