The Artwall (see artwall.unyt.org) is a collaborative art project for unyt.org trade shows and events.

The project is about creating a joint digital artwork with strangers.

In a transparent canvas each participant can color the pixels of a certain own area (30x30) with a 16-color palette.

The repository implements front-end rendering.

1. Install the UIX command line tool following the Getting Started guide in our documentation.

2. Clone this repository to your local machine:

   $ git clone https://github.com/unyt-org/example-artwall

3. Run the project local

   $ uix -wlb --port 8000

4. Navigate to your favourite web browser and open http://localhost:8000 to see everything in action.

This diagram outlines the UIX default project structure. We split our code base in back-end, front-end, and commons folder.

In UIX, Pointers are a fundamental concept for managing shared data across different parts of your application. Pointers allow different components or endpoints to access and modify the same data. In the context of our game, a Pointer could represent the x,y and value of a pixel.

Pointers are synchronized over the Supranet, based on our powerful DATEX networking protocol that ensures real-time updates and consistency across endpoints. When one user draws a pixel, the changes are propagated to the other players through the Supranet, keeping the game state in sync.
