I would like to hide an easter egg in my document by replacing the last full stop of my conclusion with a (vector) image scaled down to pass as a punctuation, almost like a microdot. Is this possible to do without too much work?
The image itself is an SVG which I have converted to a TikZ image using InkScape, but if another format is better suited for this I can convert it again. The document is going to be published as a PDF so I'm hoping that someone with a keen eye may notice and zoom in enough to see the image.
