I once had a job where I was writing a script that would produce layout files for a machine that would print images to microfilm. One of the requirements was that each section should have a header image with information about the section and signed by me, so I wrote as part of the script something that would generate the image and include an svg of my signature that I had created. Ended up looking pretty good.

I have no idea what they would have expected me to do had I not done that.
