Of course! 😃
It's an early demo I've put together shortly after the core came to life for the first time.
It uses a MAX7219 LED display - 4 of them in series as a module.

The font and the display graphics functions are borrowed from there with some modifications.
The display driver library is this: https://github.com/bozont/LedControl (it's a fork of the original LedControl - but this one uses hardware SPI to be really smooth and fast)

Here's the sketch:

I've tested it quickly with a Nano Matter:
