A "tippy cast" is simply a feature cast (nose, eye, lips, ear) that has been turned on a strange angle, so that the the object has been reduced to a more abstract physical representation of shadow and light shapes. "Tippy casts" are extremely useful to learn how to see shapes, distances and other basic measurements accurately and rapidly. We are meant to finish each study in four hours, and I have personally found it to be an exceedingly helpful exercise. Most students find that their ability to judge tilts, shapes and distances improves greatly during the months that they spend on these studies.
