I like this Panasonic phone too, which apparently comes with a 128 gradational LED light called 'Hikaridrops'! What does this mean? It means the outside of the phone offers 10 variations of illumination pattern with stunning resolution.

Why it reads your emotions of course, by analyzing your voice as you chat and displaying different patterns and emotions on the front of the phone - presumably so everyone can see how annoyed you are wiht the person on the other end, as well as hearing your irritation! Most useful!
