The iHolo is a concept phone that combines the design of the new touchscreen iPod Nano with futuristic technology. It is designed by Kingyo Xie who previously created the Mercator concept.
At first look, the iHolo is a tweaked touchscreen iPod Nano and it is. But maybe an iPod Nano from the future that you can use as a phone.
The name as you guessed is derived from the word hologram and naturally it is one of the key features of this concept device.
The hologram enables you to have a very tiny device but also have excellent multimedia and gaming capabilities. The hologram can also be used as controls for games etc.
