HashThySelf is a new kind of search engine based on a patent pending concept and method. On the realization that identity matches are of interest only to a select few (probably in CSI Miami and the like), the developers decided to architect a solution for those who are simply interested in likeness matches.
They also decided to add a unique character to the service making it fun (some say difficult) to use and easy to recognize. When you submit a photo, the Hashing engines search the web for other photos, hopefully of other well known people, that are similar to the one you provided.
You then get a list of "hits" or ranked matches to your submission on the results page. Try it out and make some new friends!.
