Star Wars Crawl creates a scrolling opening crawl with your own text.
The crawl is a perspective transform: the text plane is tilted away from the viewer so the top is further off, and then scrolled upward along that plane. Text shrinks and converges as it recedes, which is what produces the sense of depth.
In 1977 there was no way to do this digitally. The original was shot physically, with a camera moving over a large printed sheet of text laid on the floor. A CSS transform now does in three lines what took a specially built rig.
