It's only been three decades, but it might as well have been three hundred. These Japan Computer Graphics Lab demo reels show just how far computer graphics have come in such a short span of time.
The graphics look dated, sure, but not bad. Many of them have more visual style than current "realistic" generation graphics. I quite like them.
There are two clips; one dates from 1984, and the other dates from 1985. In the link before, there is another clip from 1983, which is worth checking out, too.
Magical stuff.
