The slick A9 search engine from Amazon.com has switched from being based on Google and is now based on Microsoft's Windows Live search. Microsoft's search is pretty good, and quickly getting better, but I miss A9's nice automatic inclusion of images from Google Image Search.
A9 does, however, have less useful but interesting additional image search columns, including Flickr, and the… "Specimen Image Database", describe by A9 as follows:
Search for images of a specific taxonomic species. This is currently restricted to images of lice.
