I made this animation to ensure, that it would be possible to combine rotation, scaling, and offset in one operation with the step-transform.scm script: I generated the same sequence twice (well, one step less in the second run), and reversed the first set of layers, with reverse-layers.scm, to make it loop.
You need a VRML Viewer to interact with the 3D model of the pencil, that was used to create the source image. A paintbrush might have been slightly more relevant, but it lost too much detail in the scaling process.
