Here's the official Star Wars: The Last Jedi trailer gone retro. Recreated on a 1984 Apple IIc computer, New York-based illustrator Wahyu Ichwandari used a KoalaPad from the 1980s and Dazzle Draw, a bitmap paint program from 1984, to illustrate this video.
According to Mashable:
In the '80s, the setup was deemed the "most complete computer graphics system," but it's clear from his process how far we've come.
For instance, in order to draw in layers for the animation, the illustrator had to draw each layer by hand, using plastic sheets held over the monitor, to trace each frame from the trailer, for reference.
Over the course of three weeks, he used 48 floppy disks (remember those?), each with 140KB of memory, and produced 288 image files which totalled a whopping 6MB in size.
Here is the official modern trailer for comparison.
