I knew I should have invested in that fancy self-balancing one, oh well.

Ah, don't worry. If you just append to one side always and do an anti-balancing one, you get a string of lights.

Mine looks weird but it's decorated:

    @star
    @lights
    @balls
    def christmas_tree():
        n1 = Node()
        n2 = Node()
        n3 = Node()
        n4 = Node()
        n5 = Node()
        n6 = Node()
        n7 = Node()
        n8  = Node(n1, None)
        n9  = Node(n2, n3)
        n10 = Node(n4, n5)
        n11 = Node(n8, n9)
        n12 = Node(n6, n7)
        n13 = Node(None, n11)
        n14 = Node(None, n12)
        return Node(n13, n14)

Lovely idea but please spare a thought for people using a screen reader! Imagine having ASCII art spelt out to you character by character, line by line.

This really is a job for a LLM.

With apologies to screen reader users: "space tab space space asterisk new line space space tab space new line space space space tab pipe new line ... forward slash o full stop full stop backslash ..."
