# Old man yells at X — Slack emoji generator

Make an "old man yells at" Slack emoji: drop in any logo and Grandpa Simpson shakes his fist at it. Transparent background, 128px, static PNG or animated GIF.

## How it works

This tool runs entirely in your browser using canvas compiled to
WebAssembly (or the Canvas API, where listed). Your file is never uploaded — it is
read into memory, processed locally, and offered back to you as a download.

## Using it

1. Open https://gif.statico.io/old-man-yells/
2. Choose a file, by drag and drop or the file picker.
3. Adjust the settings. Grandpa Simpson shaking his fist at any logo.
4. Set the filename and download. Names are slugified so the result can be
   uploaded straight to Slack as a custom emoji.

Results are also saved to a per-browser history at https://gif.statico.io/history/.
