Laura Lee Donoho at the Wide Awake Cafe links to a site where a face recognition program compares your photo to those of celebrities and lets you know who you look like.
The first one was Nicole Kidman which was very nice for me.
Others were Julie Christie, Sean Astin and Benjamin Netanyahu.
They do give you a percentage for the match. Nicole was 65%, Julie was 54%, Sean was 48% and Benjamin was 45%
