This makes me so very curious to try out a Dactyl.

I bet you could pilot a submarine to the bottom of the ocean with that

I love my Dactyl Manuform - Been using it for a few years now and loved every moment of it.

Been planning to print+build a second one with the trackball built-in, but I can’t find a generator that includes all the options I want, and I have yet to take the time to comprehend openscad. I have bought the parts I would need for it though, so I can eventually make it happen.

You got balls.
