Log in with your face

Hello guys recently while i was surfing over the cnet downloads i found this one. please check this out.
 A new app called the key lemon which is a face recognition software which allows us a cool feature that we can use our face as our password for login in our computers or laptops.
 i think this one as very intresting. if u need to download this click here. This is working in xp,vista and also in windows 7 but he only sad is that its not a freeware.
 To know more about this software visit the downloads blog here.
