My doctoral school organizes an internal "doctorand day" where doctoral students from different domains are supposed to present their ideas to each other. As far as I know nobody really sees the value of this but participation is mandatory. The program committee assigns every participant either a talk or a poster. A talk means you talk for 10 minutes and then you go home (/back to work). A poster means you need to be there the whole day. Now, I got assigned a poster. I can't make them give me a talk, but I can try to make them regret giving me a poster (spite is a strong motivator for me, and I like to think I use it constructively). So since I'm already recycling my topic from my TYPES talk, I decided to recycle the slides as well. Fortunately I had 8 of those, so perfect for just laying them out in a 2x4 grid. I now have both the slides and the poster importing the same slides-contents.typ file which defines all the text and revealing behavior. I'm only overriding polylux's alternatives-match function to work with handout mode, and everything else just works. I'm pretty happy with it!
