Introduction ============ Gillcup is a 2D animation library. It is intended for both scripted (i.e. the entire animation is known ahead of time), and interactive animations. Gillcup is modular: the core provides a timer and animated objects with nothing relating to graphics. Visualization classes based on Pyglet are provided in the :py:mod:`gillcup.graphics` module. Gillcup depends on nothing but Pyglet_, easing deployment. Pyglet, in turn, depends on Python and OpenGL. .. _Pyglet: http://pyglet.org/
