Many years ago, in the mid-1970s, there was a construction article in,
I think, Popular Electronics magazine, for basically a blinking light
panel. It had a field of LEDs that blinked randomly, nothing more. The
article stated that the blinking lights on large computers of the day
were simply there to impress their owners, and that "a painted metal
panel would convey the same amount of useful information". Since such
machines were prohibitively expensive for the hobbyist, there should be
a way for the average hobbyist to "get a decent set of blinking lights",
hence that construction project.
The article's author was clearly completely (and dismissively!)
clueless about what computer front panels are really all about.
