I got back to playing #FlightOfNova lately, because it's dark and calm and meticulous. A great game to play in the winter. Dawdling around in the settings I noticed it had #headtracking support for looking around the cockpit. I quickly considered getting one of those silly devices, before I remembered that #Opentrack supports any old webcam. *sounds of rummaging around* So that works great. Just use "neuralnet tracker" as input in Opentrack.
