Mine would be creating pen and paper ciphers for my made up secret communication needs.
I was learning Gregg Shorthand at some point just for the fun of it and every time I brought it up people had no idea what I was on about.
I’m old enough to remember when shorthand was a required course for women in secretarial schools. I always though it was black magic and very cool.
Wow. How old are you?
In my 60’s. According to Internet sources, shorthand was taught in schools until the 1990’s. It’s likely that shorthand use declined as PCs became common in offices.
I try to make something that looks good (or at least doesn’t look like random static) by running pictures I’ve taken through audio editing software. There are some extra steps that go into it to “trick” the program into importing the picture as if it were a sound file, making sure the header (information that tells your computer that this is a picture) doesn’t get fucked with, and then exporting the data in a way that it will be saved as a picture and not an mp3 or something else.
On the rare occasion I do bring it up, I can literally watch people’s eyes glaze over. Until I show them a picture
Edit: internet is really bad right now, will reply with an image when I can
Edit2: picture was too big at 7MB. Hopefully a screenshot of the picture doesn’t look too bad
