 **SmartCube** is a tiny and customizable desk toy using the ESP8266 D1 Mini.
 Built entirely from cheap, easy-to-find parts, it can connect to Wi-Fi and can be programmed to do just about anything:
-show notifications, display the weather, monitor stuff, show a clock, serve a web site, be a virtual pet or whatever else your caffeine-fueled brain can imagine.
