There should also be a Latex library (?) that makes your documents look like they were photocopied, so you can use the coffee stains and the photocopy to make it look like you spent long nights working on your assignments.
Haha that first one's great, addresses (what is sadly) a real need.
I've seen that cthulhu-worshipping madman one before, but the results are disappointing. I'm sure much better can be done in that direction. e.g. (is this the most famous SE answer of all-time?) https://stackoverflow.com/questions/1732348/regex-match-open...
There is also a wine version, if that is your preference: https://www.overleaf.com/latex/examples/latex-wine-stains/cd...
