John53588 just shared a new project: "NeoPixel Mini Cube"
This mini cube is made up of six 4x4 WS2812B panels giving a total of 96 individually addressable RGB LEDs. Buried inside the cube is an ATTiny85 microcontroller powered by a 120mAh Lithium-Ion battery. It also contains a mercury switch and a couple of transistors to turn the cube on. The cube switches itself off after displaying a series of animations.
All the files needed to create this project are downloadable in the ZIP file at the end of the write-up
