Designer Park Hyun Jin has created a concept laptop which can fold.

An excerpt from the source 

The LIFEBOOK X2 concept takes a different approach to portability. It’s not only thin, but also folds into quarters which leads to some interesting features. Open the LIFEBOOK X2 halfway and you have sort of an ultra widescreen palm top. Unfold it completely and you have one full size notebook. This denotes a seam running right across the LCD which is enough for me to dismiss it but the idea is intriguing. What’s say you?

Some pictures from the designer..
