[ID: An MS Paint drawing of four original characters for the book Flatland: A Romance of Many Dimensions. Each is a different 2D shape, labeled with their name.
Victor Nietra is a square, covered in a pink, orange, and green pattern with a single purple eye like a weird blobby fish looking up at the camera. He is in the top left corner of the image, looking down at the rest of the characters.
From left to right, Billie Oakley is a Straight Line who is a very thin diamond shape, with two red eyespots, and stripes of black, green, orange, and purple.
Next to her is her mother, Bernice Oakley, a longer Straight Line shaped like a long, uneven rectangle, with a single purple eye, and almost symetrical stripes of black, purple, green, and orange.
Next to his wife Bernice is Frank Oakley, an Isosceles triangle with a similarly pink blobby shape with a single red-brown eyespot, with the pink blob surrounded by green and orange with flecks of white.
