Imagine mode:
Every post on your feed it fed into midjourney, and you scroll those instead

Ghost chatter:
Everyone you follow is given a point in your place of residence, and gps/accelerometer is used to position you.

Then everyone’s posts are fed through text2speech live, so you can walk around and listen to what’s happening

Mutual of the day mode:
Every day one of your mutuals is randomly selected, and you can only view and interact with their posts that day
