This 10×10 LED matrix uses individually adrressable LEDs (WS2812) connected to an ESP8266 chip running the WLED software so it can be controlled via Wifi using the app or a webbrowser.  The pictures above are custom made pixelart uploaded to the matrix. The enclosure is designed using Fusion 360 and 3D printed. The front is a 1mm thick 3D printed plate used as a light diffuser. The diffuser combined with a 10×10 grid of boxes results in a nice pixelated look.
