28F Ireland. Tell me what you’re currently far too interested in

I have an hour to kill and apparently I’ve decided that making new internet friends is how I’m spending it.
I’m 28F from Ireland, historian/law person by education, chronic cross-stitcher, art obsessive, recently qualified driver (still enjoying the novelty of being legally allowed to just… go places), and currently sitting at my mother’s graduation reading The Art Newspaper because I foolishly left my stitching at home.
I’m into art and art history, early modern history, museums, books, music, cross-stitch, wandering around old buildings, unnecessarily elaborate day trips and generally learning things I absolutely did not need to know. My interests tend to arrive with alarming intensity.
I like people who are curious, funny and capable of having an actual conversation. Tell me about the niche subject you could give an unsolicited 20-minute lecture on. I genuinely want to hear it.
Platonic only, preferably around my age-ish, and bonus points if you’re in Ireland/UK/Europe because time zones are considerably less annoying.
So: what are you currently obsessed with, and why should I become obsessed with it too?
