The Eames Lounge Chair was designed in 1956. At no point since then has it looked dated. And it never will. It's timeless (and comfortable as well). http://www.hermanmiller.com/products/seating/lounge-seating/...
Its difficult to make timeless work with software because the capabilities and mediums change so rapidly. But we'll get there eventually.

To the people discounting timeless design: yes most of contemporary industrial design is disposable, but some pieces from Braun and Apple will be considered classics.
I would never pay for a Picasso or a Van Gogh to hang in my house (because it's would be exorbitant and) because it doesn't evoke positive emotions when I look at it. Norman Rockwell does just that and he has since I was a kid, does that make his art better than Picasso's? Not to most people.
Just because ideas about how a chair can be designed remain popular doesn't mean that it stops being subjective.
