* [Optimus Maximus](https://www.artlebedev.com/optimus/maximus/) keyboard has OLED screens below the keys, which are transparent, so that the symbols or icons under the keys can be changed.
## Screen
* Pixel Qi
* [OLPC display](http://wiki.laptop.org/go/Display#Understanding_the_display_system)
The OLPC (One Laptop Per Child project) integrates a Pixel Qi
screen. This screen uses subpixels (red, green, blue) with a square
aspect ratio using a non-traditional layout of the subpixels. It
features a reflective higher-resolution black and white display,
which works in bright sunlight. Behind that black and white layer,
there is a backlit screen with colored pixels. This means that
depending on the lighting of the environment and backlight
brightness, the color may fade away, but a crisp black and white
picture will always be visible. This also allows for reduced power
consumption if the backlight is disabled or its brightness reduced.

The GVCS aims to design construction kits for 50 industrial machines
which would be necessary for a self-sufficient village. Among these
are the compressed earth brick press (used to make bricks for
buildings), a tractor, a wind turbine, or the Fabrication
Construction Set which can be used to build the other machines.
