This Eclipse Intuit Phone designed by Eddie Goh has a unique concept. Its features powerful 5 megapixel camera, with built-in software for editing and uploading to a photo album, slide-out touch keyboard with tactile feedback, and a nice big touchscreen front and center. Parts of the phone are made from a chemically based thin solar skin to charge the battery when exposed to any kind of light. This is why it's unique. Anyway it's only a concept cellphone but the technology is possible to be done.
