Once completed, this sculpture looks like a Christmas tree. Chop out eight squares on the top of the grid from both sides so only the middle square is left untouched. Then chop out seven squares on both sides. Chop out another seven squares on both sides. This will leave three squares untouched, both times, in the middle of the grid. Next, chop out six squares on both sides, then another six squares. This will leave five squares untouched in the middle both times. Then chop out five squares on both sides, then, once again, another five squares. This will leave seven squares untouched in the middle of the grid both times. Then chop out four squares on both sides, two times. This will leave nine squares untouched in the middle of the grid. Then chop out three squares two times from both sides. This will leave eleven squares untouched in the middle of the grid both times. Then chop out only two squares on both sides. This will leave thirteen squares untouched in the middle of the grid. Then, on the bottom of the grid, chop out seven squares on both sides, leaving three squares untouched in the middle of the grid and you're done!
