Four relativistic spinning particle models (vector oscillator, spinor oscillator, spherical top, massive twistor) describe identical physics in free and interacting theories within the spin-magnitude-preserving sector.
A constrained supertwistor approach to the D0-brane is developed, related to the spinor moving frame method, and quantized to yield the spectrum of the massive counterpart of linearized type IIA supergravity.
