Gizmodo had a cool post yesterday about Suhyun Kim's concept for a "visual mobile phone." You can see the information on Yanko Design here. The phone can take text and voice input and converts them to either voice or text, respectively, allowing a person who cannot hear to use the phone.
...Anyway, I think this thing is awesome. I can just imagine other people being jealous of my phone if I were able to buy one of these and it looked like that. There is just not enough adaptive technology that looks good, too. So much of it is still beige and blocky. This is cool!
