A laptop serves as my main computer at work (with an attached monitor, keyboard and mouse, as I hate laptop keyboards and touch pads.) The laptop's video card is incapable of accommodating an added monitor as an extension, it merely mirrors the same display. That is distracting. You might say, "Close it partially to the point just before it powers off." Tried that. Distracting. So I covered the display with my copy-holder-clip-thing. Boring. So I took a picture of the thing and made a picture in a picture in a picture in some sort of Dali-Escher absinthe-fueled infinity-nightmare and stuck it in the copy holder. Distracting.
