I keep seeing SunBurst Background Pattern for years, literally! and it is still trendy. Why is it still so? Do we lack creativity for similar generic (or focus drawing) background patterns or human psychology has bias against it?
Secondly, have there been any other so obvious background pattern trends?
Note: I asked the question in graphicdesign.stackexchange at first. Having got no answer and having doubts on the appropriate site for this question, I decided to ask here as well. If this parallel questioning against the rules of SE, I might just as well delete one.
A few examples from a Smashing Magazine piece on website backgrounds.
