This is an Adafruit MagTag project in two parts.

The github code handles talking to a web service (The Cat API), retrieving a random cat picture, scaling and dithering/quantizing it to greyscale for the MagTag, and then feeding the MagTag the image in a sort of super stupid bitmap format.

To use:

1. Get an API token for The Cat API.
2. Download a release
3. Run it somewhere MagTag can access with -api-token=YOUR-TOKEN
4. Edit magcat.py to update the URL (keep the /raw at the end!), save it and the contents of lib/ as code.py to a UF2-using MagTag
