20-30 years ago I saw a search engine, kartoo.com, where the results were displayed visually instead of in a list. It now seems to not perform that function, but produces a list. It’s a little difficult to search for that kind of search engine, because google will think you mean a image based search engine like tineye.com. Two sites that give an example of what I mean are

http://www.liveplasma.com/ which shows results for similar or related musicians, and

SEO Keyword Graph Visualization | SEO Browser - TouchGraph.com which days it will arrange the results in a web or spider diagram a little like kartoo did.

Tbh I think I personally prefer lists, but I thought it was an interesting concept. Google itself has kind of incorporated the idea (at least in image search) in that you can press a row of horizontal tabs about the areas it thinks you could be searching for.
