This interesting concept comes from designer Billy May. The OLED Blackberry is a combination of a Blackberry 7130 and an Optimus Keyboard. This OLED Blackberry was designed for the Mozilla Phone project, and obviously it takes the best of both devices and creates this stunning concept seen above.
The OLED keys, just like on the Optimus Keyboard can be programmed and change their look. It looks stunning and the minute you see it, you realize that you are looking at a device that has some actual richness of personality and could provide a richer experience.
