In Search of a Good Design
Some may argue Google's logo looks silly. Then again, so did most other things on the Internet in the mid-1990s.
"It was playful and deceptively simple. The design subtle as to look almost non-designed, the reading effortless. The colors evoke memories of child play, but deftly stray from the color wheel strictures so as to hint to the inherent element of serendipity creeping into any search results page and the irreverance and boldness of the “I am feeling lucky” link. The texture and shading of each letter is done in an unobtrusive way resulting in lifting it from the page while giving it both weight and lightness. It is solid but there is also an ethereal quality to it."
