 As part of the construction of this book and my art practice I made an ecosystem of tools to create, display, share and curate shaders. This tools works consistently across Linux Desktops, MacOS, [RaspberryPi](https://www.raspberrypi.org/) and browsers without the need of changing your code.

-**Create**: in order to illuminate the experience of coding shaders I made an online editor called [glslEditor](https://github.com/patriciogonzalezvivo/glslEditor). This editor is embedded on the book's life examples, it brings a series of handy widgets to make more tangible the abstract experience of working with glsl code. You can also run it as a standalone web application from [editor.thebookofshaders.com/](http://editor.thebookofshaders.com/). Learn more about it [here](https://github.com/patriciogonzalezvivo/glslEditor).
