Polaroid photographs of Lisa screens

<p>These are scans of one of kind Polaroid photographs (and two printouts) taken by Bill Atkinson documenting the evolution of the Apple Lisa graphical user interface over its development in the period from 1979 to 1982, including its initial transition from an HP-300 inspired softkey interface to the Xerox PARC/Smalltalk-inspired GUI early in the project, early experiments with windows, menus and menubars in various locations, to the implementation of the desktop with icons towards the end of Lisa&rsquo;s development. Atkinson himself personally experimented with and implemented many of the early design iterations of the GUI, in collaboration with Larry Tesler who was running user testing. Atkinson would do the programming at home at night, and bring the new version of the software to the office during the day for user testing and feedback. Atkinson was thoughtful enough to photograph the evolving Lisa UI over time. Also included are screenshots of a Lisa drawing application, the precursor to MacPaint, as well as experiments with halftone dithering algorithms for showing scanned photographs on a monochrome display.&nbsp;</p> <p>A discussion of these images can also be found on Folklore.org, a websire hosted by the Computer Hisotry Museum. <a href="https://www.folklore.org/Busy_Being_Born.html">Here</a> the specific entry discussing these images.</p> <p>&nbsp;</p>
