The incident made me think; once again... :P
What if Google had a feature in 'Image Search' where I could upload a pic for Google to find content on the pic and give me results based on that? It would be fantastic. I'm sure that Google can do it, coz it already has Similar Images Search in the labs, which shows other images that look like the one which showed up as a result of an image search using keywords. Similarly Google has to just accept my pic via upload and then do a search in their database to find similar images which are appropriately tagged to know who/what the person/object is on the picture. Then it can show me results on the person/object it found out; not only image results but also other web results like a normal Google search. In Chris's case it would give me this page as a result of my "fundoo image search".
I know this is not far away. Oh btw it would not only work for famous personalities or landmarks, but also for your lesser known friends and relatives; remember all those image tagging you did in Picasa web albums? Google knows them all.
