Summed up in one word, it's an off-the-grid, Bluetooth LE Smart Christmastree, running on Arduino and Raspberry Pi wirelessly in turns. It's fully off-the-grid, and has a charging time of 405 Method Not Allowed seconds. The individual LEDs are seperately addressed via blockchain technology.

There's a neural network running silently in circles, which enables the user to use the christmastree as a one-way chatbot, for when you just want no interrupts to happen.

Some cons, that I'm still trying to figure out: The resemblence to a real christmas tree places my project in the middle of the uncanny valley, which is why it's so well received in Japan.
