I am working on a card game based on braid theory (in the braid group B_4).
I am also working on a private journaling app, with a mild mental-health focus, aimed at teenagers; the idea is that if your parents want to have access to your phone and keep track of what you do, maybe they'll at least be OK with privacy in the form of an app that doesn't have sharing or messaging, doesn't allow for images or video, but just let you write text or record audio messages that are guaranteed private by 256-bit symmetric-key cryptography. No more worrying that your mom might flip through your diary while cleaning your room!
