[IBM]
1. Apparently random flashing streaks on the face of 3278-9 terminals
while a new symbol set is being downloaded. This hardware bug was
left deliberately unfixed, as some genius within IBM suggested it
would let the user know that `something is happening'. That, it
certainly does. Later microprocessor-driven IBM color graphics
displays were actually programmed to produce green lightning!
2. [proposed] Any bug perverted into an alleged feature by adroit
rationalization or marketing. "Motorola calls the CISC cruft in the
88000 architecture `compatibility logic', but I call it green
lightning". See also {feature} (sense 6).
