The entire movie embodies Cassette Futurism, but IMO the self-destruct sequence is particularly great. The entire process looks so satisfying that I probably wouldn't be able to stop myself from running it if I were one of the crew.

This and Bladerunner is on my watchlist.
This is one of those movies that sticks with you. The aesthetic blows me away every time, from the very beginning. The sets are incredibly cassette-ey while super sleek and modern for the time, and obviously fully practical. Quite possibly my favorite movie in terms of set design. You can tell the overall design is timeless because it changes very little across the decades that they’ve been making Alien movies.
