== [css-paint-api] use-case: data/audio visualization ==
Good evening,

Has data- and audio-visualization been considered as a possible use-case of the PaintWorklet? (both static and real-time audio visualization)

Currently, it seems there is no way to communicate with a PaintWorklet from other threads. If a MessagePort or a SharedArrayBuffer could be sent to the PaintWorklet, considerably more options would be available with this API:

```js
let channel = new MessageChannel();

await CSS.paintWorklet.addModule("vis.js");

CSS.paintWorklet.modules["vis.js"].postMessage({
  messagePort: channel.port1
});
```
