Google Correlate has graduated from Google Labs and can now be found in Google Trends from now on.
For those you haven’t had chance to use these tool before or doesn’t know it existed:
It is a tool finds search patterns that correlate with real-world data. This tools combines search terms with their popularity over time or throughout different regions which enables you to search for trends within the context of a time period and season.
I personally like Search by Drawing Features, which is somewhat funny and informational.
