Christmas Tree Xkcd. Contrary to what the terms root and leaf might imply trees in computer science are typically represented upside down with the root on top and the leaves fanning out below. This means you re free to copy and share these comics but not to sell them.
Once the tree is cut down it will eventually start turning brown and or losing its needles as it no longer receives any nutrients from its roots. At the top appears a complicated spectrum possibly that of a white led representing the tradition in some cultures of putting a star or an angel but still usually lit at the top of the christmas tree. Beneath it is a heap of presents sorted with the largest on top smaller presents connected to it with string.
