3 ideas:
1. hook up a really standard machine learning model to get back labels and bounding boxes of things in the world. Put game screens over them describing name, status affect and other attributes.
2. corner monsters. In 3d corners (of a room) generate a cobweb or a small monster
3. social distancing ghost. Ghost of covid past occupies spaces shorter than 6 feet wide between people. Involved, would require person labeling and distance calculation algorithm
