A completely random thought: is there a name for the motion of a carousel horse? One of those would be informative and impish:

1. Donusoidal
2. Torusoidal

[For you overly serious types - Yes, I know that both of those answers are incorrect because 'donut' and 'torus' refer to 3-dimensional surfaces. My question and answers are not meant to be geometrically correct. However, if there really is a term describing the combination of sinusoidal and circular motions of a carousel horse, I would like to know what it is.]
