The Stands4 network is a company that specialises in creating small, very niche search tools, such as Lyrics, Poetry, Biographies and Symbols.
Their latest is Anagrams and Scrambles at http://www.anagrams.net/ - these are listed in a variety of categories. For example in the Classic writers category, an anagram of Thomas Hardy is 'hot shy drama'.
You can also reverse this - search the anagram 'midnight kicks' to discover Dick King Smith.
A nice tool for crossword puzzlers.
Other resources are Abbreviations and many more.
