There is no such thing as a perfectly designed item. There are those that are well-designed and should be admired for their aesthetic beauty, functional aptitude, and/or general improvement of a specific experience, but every item (products, websites, content, processes, ...) can be improved in some way or another. Every one of them. What was your initial reaction when you first interacted with a first generation iPhone? It was likely that you were stunned by an incredibly beautiful and wonderfully intuitive device. But the iPhone 4 is undoubtedly an improved (yet still imperfect) product.

And "well-designed" doesn't mean that the item has to be particularly beautiful to look at. Take fonts for instance. The choice of font can make a huge impact on everything from brand recognition to content readability. I recently ran across an article that described a font designed specifically for individuals that suffer from dyslexia. Use of the font has been proven to dramatically decrease the number of reading and comprehension errors a dyslexic individual makes. Well-designed indeed. Kudos to StudioStudio for taking this project on.

And what about other, more mundane items? One of the original designers of the iPod, Tony Fadell, created a company called Nest that has redesigned the thermostat. There's no question that his product is beautiful. And if it is easier to use than the archaic blocks that most of us have in our homes, Tony will make a serious business out of it.

Lastly, here's a different sort of redesign to tickle your brain with...the revamping of the supermarket experience. Tesco's "virtual supermarket" in the subway of South Korea is nothing short of genius.
