Nice, I had seen that. Ideally it wouldn't be something that sits on my desk. I want to hold it and talk to it and build spacial awareness with it. But fits many of the goals. I'll have to give it a try!
Consider that you could buy the smallest version, disassemble, and add a Raspberry Pi or equivalent to bolt compute and wireless comms onto your desired interface, if only to prototype form and function. Looking forward to seeing what you build!
