Maybe they are too small for a startup, too weird for work, too niche, too much effort, or just too far down the backlog.
I wonder if it would be fun to have a thread where people pitch those ideas.
If you have something you would like to see exist, but probably will not build yourself, post it here.
Could be software, hardware, data, art, local tools, research, weird experiments, anything.
I'm curious about your ideas!
It seems like once encryption took over the art of codebooks kinda went away but I still find the history of them really interesting and think a modern take would be fun to build.
