I don't know what you mean by "looked good"; there's obviously a trade-off here between beauty and utility. To me, a UI "looks good" if I can immediately understand how it works, and if it presents the information in a meaningful way. To a layperson, that may look "not good"; they may prefer something with more color and detailed imagery that looks more like a real-world object, even if (possibly unbeknownst to them) it's harder to use. Of course, being able to understand how to use an interface is partly affected by what you're familiar with and, in turn, what you were exposed to in your formative years. For me, Windows 95 – early-OSX-era interfaces have 'the best' look.
