Here is another cool programmable clock with WiFi connectivity. The Foxie Clock 2.0 is inspired by Nixie clocks but is much smarter. It has a built-in light sensor for automatic brightness control. This clock has a PXL mode too.
The Foxie Clock 2.0 comes with a dark clear acrylic lid for the PXL mode. These clocks are made from various woods, including cherry, walnut, and sometimes exotic woods like Zebrawood, so each one is unique. They are internet connected, so they sync time at boot and roughly every 3 hours.
