CGI and proto-CGI

Good call from John Michael Boling on spotting this '70s Levis commercial--all analog, anticipating the look of CGI. Some real chicken/egg stuff here: Is CGI a style or did it follow the look of what had been predicted for it? As for the Friskies commercial posted by Paddy Johnson that Boling was responding to, I laughed at what was probably the unintended irony of the cat re-emerging from this sublime, tripped-out landscape to greet a lousy can of commercial cat food. Talk about a letdown. Or perhaps the cat's "trip" is what an ordinary can inspires--that's how uncritical felines are when it comes to a meal.
