From Wikipedia:
The Point! is a fable that tells the story of a boy named Oblio, the only round-headed person in the Pointed Village, where by law everyone and everything must have a point. Nilsson explained his inspiration for The Point!:
"I was on acid and I looked at the trees and I realized that they all came to points, and the little branches came to points, and the houses [each] came to [a] point. I thought, 'Oh! Everything has a point, and if it doesn't, then there's [still] a point to it.'"[4]
