|Left: Original Star Trek series. Right: Star Trek: The Next Generation|
Star Trek: The Next Generation didn’t have as much money for set design as did the original series, which had panels wired with jewels and glowing buttons. Instead, they cut out sheets of film and put them over glass panes. To this day, people still modify their computers and tablets to make them look like an LCARS device from the 24th Century, by way of the late '80s.
