I had never heard of Google Image Swirl Labs until today when the domain showed up in my stats.
About Image Swirl from Google:
Google Image Swirl organizes image search results into groups and sub-groups, based on their visual and semantic similarity and presents them in an intuitive exploratory interface. Try this tool to resolve an ambiguous query visually (apple, jaguar, beetle) or to explore a concept from different visual perspectives.
Although I received a referral from Google Image Swirl, the search query inexplicably pointed to a page with no corresponding alt tag or description containing the search term.
Google Image Swirl has a limited set of predetermined available images for viewing.
Each Image Swirl search is auto-filled with the closet available set of images via the spelling of words as they are typed in.
To see a list of potential images to view – type each letter of the alphabet in the search box – one at a time.
