Make webms of your CAD model with a 3d illusion effect.
Requires ffmpeg.
Run the script, then you will have 5 seconds to setup your screen and place your cursor, then don't touch your mouse. The script will drag the mouse in a circle taking screenshots, then convert them into a webm animation.
Frames will be stored in a "frames" folder in the same folder containing the script. Note that when the script is run, any previous folder and its contents will be deleted.
