When I’m working on something, I spread papers everywhere. I’d end up covering the user interface.

Easy? Since there are no buttons, this must be “simple”, right? All I need to do is learn how many thumps and where to thump. That blank square the feel good website presented was so inspiring. Everyone knows that you thump a square a few times in a corner and change the temperature, play music, or whatever. Maybe the thing works with Morse Code and one button does everything. A visiting relative will instantly know what to do.
