Asirra forces you to spot the cats

Long gone are the days when you have to prove that you are human by typing in a jumble of mangled letters and numbers that even a human has trouble deciphering (I often get it wrong). Here comes Microsoft to the rescue with the Asirra project. The short is that the Asirra project provides the code that lets you prove your human by choosing all the cats from a series of pictures of dogs and cats.

Not sure this is the solution to the anoyounce so many people have with CAPTCHA* but I think its moving in the right direction. Computers will get faster and deciphering letters and numbers will become trivial no matter how mangled they are. A better solution is needed.
