Created in Cinema 4D. This one was put together over a few nights. Definitely took a bit of math to get the right cog and rotation ratios. X-particles tracer was used to draw out the spirograph. The corners aren't perfect on the spirograph and in retrospect I think I should have increased the duration of the project and then rendered out every other or every third frame so that the corners are all perfectly round. Really loving exporting to an .otf file so that I only have one file that contains all my multipasses.
