Check out this cool laptop concept from designer Hao Hua.
The D-roll Laptop is designed like an artists tube, which contains a roll up OLED screen and a cool slide out keyboard, it also has a mouse and a web camera which are used as the end caps for the case.
This is a really cool design, it would be great to have a laptop that worked and looked like this, but I think this is probably a few years away yet. Have a look at our handy OLED TV explained guide.
