Thanks to series of knitterly links, I ended up at MyHeritage today (thanks to Kim of Yarn Abuse for providing the final link in the chain.) By uploading images from my Flickr, I found out that I look like a Bollywood actress, a well-respected star of stage and screen, a famous telepath, a controversial filmmaker, and the Ghost Whisperer (also on the list David Schwimmer, Sharon Stone, and Andie McDowell). The best that I can tell is that my angle and expression vaguely match the photos of these celebrities.
When I did this for John his #1 lookalike was Elvis Costello. It might have been the glasses or perhaps this says something about my taste in men.
