@ -4,9 +4,9 @@ A few years ago, assuming that everybody has a computer with a graphical process
Thanks to the [Raspberry Pi Foundation](http://www.raspberrypi.org/) a new type of small and cheap generation of computers (around $35 each) has found its way into classrooms. More importantly for the purposes of this book, the [Raspberry Pi](http://www.raspberrypi.org/) comes with a decent Broadcom GPU that can be accessed directly from the console. I made a [flexible GLSL live coding tool call **glslViewer**](https://github.com/patriciogonzalezvivo/glslViewer) that runs all the examples in this book. This program also has the ability to update automatically when the user saves a change to their code. What does this mean? You can edit the shader and every time you save it, the shader will be re-compile and render for you.
By making a local copy of the repository of this book (see the above section) and having [```glslViewer``` installed](https://github.com/patriciogonzalezvivo/glslViewer), users can run the examples with ```glslviewer```. Also by using the ```-l``` flag they can render the example in a corner of the screen while they modify it with any text editor (like ```nano```, ```pico```, ```vi```, ```vim``` or ```emacs```). This also works if the user is connected through ssh/sftp.
