It looks like Google is testing in the Google Suggest autocompletion a dynamic query based footer. Based on some queries, Google will customize the footer of the autocompletion drop down, to show a Google logo that represents the query.

@medicomkim shared some screenshots with me of this in action on Twitter but I cannot replicate.

Query: [buddism]

Query: [islam]

I wonder how many different queries can generate how many different dynamic Google footers?
