Here's a bit of fun off topic entertainment for you folks today. Microsoft has a silly and fun little tool designed to guess your age. It's actually a web-site called How-Old.net with a built-in algorithm which is practicing the old carnival "guess your age" game.
All you have to do is feed it a picture and it spits out an age that it thinks most closely fits with the image presented. Some of its predictions are laughably bad, but sometimes its pretty accurate. What's really intriguing is that it is basically a pseudo artificial intelligence that keeps getting better as it goes on.
The only limitation is that you can't upload a photo that is more than 3MB in file size. There's even a description regarding the background of the demo. Oh yeah... there's one more bonus feature... it tries to guess the gender of the person in the photo as well. Funny stuff!
Here's the link if you want to see what the site can do with a photo of you or your friends and family: How Old Do I Look
