I saw a really cool thing today...

I was standing at the counter at a cafe having a cappuccino when a woman's cell phone rang.  Instead of putting the phone to her ear, the woman held it in front of her face. The phone was an average sized cell phone but it had a very large screen in which you could see the entire upper half of the other caller.  The woman in the cafe proceeded to communicate through sign language to the person who called, who was also signing!  It was phenomenal.
