The 3D Xmas Tree for Raspberry Pi from The Pi Hut is a quite a clever PCB design. The example photo shows it bundled on a full sized Pi but it looks much "cuter" as many put it, on a Pi Zero.
You can purchase these from Pi Hut here, but only in December and there are limited amounts of stock

The great thing with this PCB is that you write your own code to illuminate each on of the 25 LEDs on the board. The Pi Hut provide a nice, simple "twinkle" effect running with Python and gpiozero library
If you are looking for some more examples I have collated the examples from the reviews on Pi hut and had allot of other users contribute interesting code, for example Morse Code XMAS Tree!
I have also made an expanded Wiki, FAQ and diagnostic Python scripts if you seem to be having trouble getting started.
