Moss is neat!
I strongly recommend you (or anyone really) read (or listen to) Gathering Moss by Robin Wall Kimmerer. The audiobook is narrated by the author, and without hearing it I genuinely don’t think I would have had the same appreciation for the incredible diversity of mosses and other small plants that were in the field I live by this year.
I remember having a PowerShot SX110IS back in 2010 and there was an open source firmware I loaded on it. I forget what it was called. It’s a damn shame that we can’t really do stuff like that anymore.
