The waggle dance of honeybees.
The angle between the food source, the nest, and the sun is represented by a dancing bee
as the angle between the straight part of the dance and vertical.
If the straight part of the dance is
20° to the right of vertical, the food is
20° to the right of the sun.
The distance to the food source is indicated by the tempo of the dance and by the number of waggles.
