I know there's a couple out there I've heard whispers about but I can't really remember them. I know you can look at the main site backwards by using Elgoog. if you type in the word "askew" in the Google search box and click search things become crooked Also if you type "Answer to life" "answer to universe" "answer to anything" the top result is the #42, which is a Hitchhikers Guide to the Galaxy reference that google programmers seemed to like. Are you aware of any of these features on Google? If so please share for my sake and possibly others as I find entertainment in some of the most simplest things.
