I'm building two things, both game related.
Over the last year I've been hacking on Table Slayer [0] a web tool for projecting DnD maps on purpose built TV-in-table setups. Right now I'm working on making hardware that supports large format touch displays.
Since I also play boardgames, this past month I threw together Counter Slayer [1], which helps you generate STLs for box game inserts.
Both projects are open source and available on GitHub. I've had fun building software for hobbies that are mostly tactile.
Cool! I was going to shamelessly ask if your DnD group had an open spot I could interview for :), but you're not in Austin.
(If you're a local reading this and enjoy DnD w/ roleplay and acting, email's in my profile)
