Such a wonderful device deserves some festive love.

An evolving Christmas card, featuring:

• falling snow
• growing trees
• festive tune(s)
• sleighs
• raindeer
• presents

(items in italic are still works in progress)

Simply copy all the .py files onto your Unicorn (via thonny, ampy or whichever technology you prefer) and reset it to launch.

Brightness and volume can be adjusted with the buttons on the right of your Unicorn.

Music can be turned on and off with the A button.

This is rapidly becoming the biggest single thing I've crafted in (micro)Python, so please forgive the Luddite manner in which I write Python code :-)
