Visualizing the motion of objects in three dimensions can be challenging for introductory astronomy students. Particular with topics such as the celestial sphere, the phases of the moon, and the seasons, students struggle to wrap their brains around the models and motions that we describe to them in our courses. The videos presented in this poster represent an attempt to help bridge that gap. They show astronomical objects moving, and from various different perspectives. The virtual camera zooms in and out, to smoothly transition to the ``Earthbound Observerion" point of view from the ``External Observer" point of view used in many textbook illustrations, so as to help students make the connection. All of these animations were created using the Open Source rendering and animation software Blender, with some additional help from the Gimp (an Open Source image processing program). This poster will describe some of the videos that have been used in the author's class, as well as the process that goes into creating these videos.
