TL;DR
Adafruit has released a new guide for PixelDust Digital Sand, which allows users to create simulated sand particle effects using CircuitPython. This is a significant shift from previous demos that required platforms like Arduino or Raspberry Pi, making it easier for users to implement these visual effects on microcontrollers. Thanks to recent enhancements in CircuitPython, particularly with the introduction of Turbo modules and the Picogame library, you can now run these particle simulations more efficiently.
