Be sure to watch the video in this linked post. Frog design has partnered with Sharp to make a new smartphone for the Japanese market. They are using Android with a high customized skin — but really the customization goes deeper than just the skin. The way to think of this is like this: base Android is a Mr. Potato head with body parts randomly put on him, this Frog version is the same Mr. Potato head with the body parts arrange correctly.
The video makes the design and interaction look fantastic — I’d love to try one out.
