The assignment was small: anchor a sign to the wall, put a machine in the room, add one interaction. I wanted to make something you'd actually want to play with. A wooden train set made sense for mixed reality because the table you're standing at becomes the playing field.

I built it alone in Unity for the Quest 3. You take tracks out of a box and they snap together. Spray cans grow meadows, forests and rocks on the table, and four buttons change the season. To get the train going you pull it apart with both hands until it fills the table, shovel in coal, strike a match and light the fire. None of the models are imported, I wrote them as code. The colors come from Firewatch and the sounds from ElevenLabs.
