Strangely, i find the UI screenshots in the article to be clearer than some modern UIs (eg Gimp). Why? I'm not sure, but maybe: (1) there is less functionality, so less stuff on the screen. (2) Black and white means that the icons are all high contrast. (3) the icon shapes are simpler (compared to Gimp's toolbar icons). (4) the borders on the forms are higher contrast; in Gimp's color picker form, for example, the boxes surrounding places where you can type stuff in appear to be gray, whereas they are black in these early Photoshop pictures.
