If you crossed a mood ring with a cell phone, what would you get? More importantly, why would anyone think of such a thing?
The people at Panasonic and NTT DoCoMo have apparently done just that, and the result is a mobile phone that changes color depending on your emotional state. The key to this bizarre feature is something called the "Feel Talk" function (so Japanese), which analyzes your voice tones and patterns while you're conversing.
Depending on what kind of day you're having, according to Gear Live, the phone can show "10 variations of brightness and colors with a 128-gradiation LED light." That sounds like an awful lot of trouble for a mood phone, but it also has a 1.3-megapixel camera, optional 2GB storage and other stuff to go with the glowing lamp.
The phone comes in four colors, but you may want to get them all. After all, you never know how you may feel about your choice an hour later.
