There was also a TRON arcade game that was a mismash of mini-games, one of which was the light-cycles:

I see from Google that indeed many, many people refer to this "use moving wall to make the other guy crash" style of game as "TRON" now, but TRON actually just put a brand name on a game genre that had been around:

"Snake" to TRON could actually be one of the earliest, if not the earliest, example of a big-budget studio movie adapting a video game concept. Doing so surprisingly directly.

Now, of course, half the movies that come out of Hollywood seem to have action bits that are vaguely video-game inspired.
