Speaking of the old six-color Apple logo, some interesting UI design history from Jack Wellborn at Worms and Viruses:
While watching the video, I couldn’t help but notice two snippets
at the 7:36 mark from 1982 about scroll bars. First, an Apple
engineer shows how scrolling works in the Lisa, followed
immediately by a similar demo from Xerox. This juxtaposition
immediately struck me as interesting because Apple detractors are
quick to reference Xerox Parc when dismissing the graphical
interface innovations of the Lisa and Macintosh. While there is no
denying Xerox’s influence, these two snippets perfectly illustrate
massive amounts of design and refinement championed by Apple
during that era. Read for yourself.
People who think UI design is easy might think the differences here are trivial; those who know that UI design is difficult know otherwise.
