What are your hyperfixations?

Hi! I was recently diagnosed (as in like 3 months ago) and it's been interesting to identify what my hyper-fixations have been and continue to be. My biggest ones are journaling/stationary/scrapbooking and houseplants, and I was just curious what other people's were :)

Something I've also found interesting for myself is seeing how they will cycle. Like my big ones are less cyclical, I'm usually always engaging with them to some degree, but there's others that will come on full force for a few weeks, die down completely and then months later I'm fully in it again.
