[ID: Four images.

The first is a book cover with a white background, titled, "The Dot and the Line", with a red circle, a blue line above it, and a squiggly black circle taking up most of the space.

The second shows the red circle and blue line, with paler red swirls and yellow shapes.

The third is a black image with white lines depicting multiple geometric shapes with numbers and letters markings points and lines.

The last is divided into four square images taken from the animated film - a red title card, the red dot and blue line in front of a yellow square, the red circle above a curled black squiggly line against an orange background, and the circle, now pink, in front of a complex blue spirograph-like shape on a black background.
