This is a place for one-off ideas that are too small or not cool enough to have their own page.

Rooftop gardens! This is Google's geospatial map of San Francisco. No greenery. If you put gardens with beehives, flowers, edible plants (grapes, strawberries!), pot, psychedelic plants you would have a small industry of people who could sell local food from their garden. I've always wanted to see if I could small batch brew beer or mead at one point so that's another thing that would be cool to do.

Any inner city or neighborhood that's having gang problems you open a weapon shop that sells every possible non-lethal weapon at below market cost at a steep discount and then let everyone shoot each other with bean bags and pellet guns.

This building has been derelict for years. Why not put a dinosaur in it? It's tall enough to support one. A bunch of old bones and a t-rex and you could charge everyone twenty bucks to go see it.

So there's this anti-tank missile that goes straight up before falling on a tank. What if you did similar but with little cameras? You have a missile that goes a half a mile in the air and shoots out little go-pros everywhere that beam all their data down to the ground so it makes a three-d location picture map of the entire area. An info-missile or something. That would be cool.

On that note this is ridiculously cool (and bougie but whatever) and reminds me of the secret societies you would have your nth level warrior wizard necrocreature take a blood oath in. I was lucky enough in my youth to travel around the world and currently there's a lack of information about the state of the world and everyone is hiding in their houses. There should be local organizations that sponsor young people to go around and take pictures and document things in order to have their own information that they know is true. If you had enough chapters you could set up trust networks of known good information. Arm them with kodak film and non-digital cameras with glass. Pens and paper. That sort of thing. Make it a bit like a right of passage.
