I'm producing tools for the following:

• converting gendered restrooms to all-gender restrooms (with or without permission)

• easy legislative templates and meetups for removing billboards from your municipality

• low-powered and repairable permacomputing hardware designs

• tools for improving home ventilation

• software for retrofitting walkable infrastructure into existing towns and cities

Something I guess kind of fits with this is doing seed-bombs, we used to do that a bit when I was young. You basically forcefully plant colorful flowers in places that are not so colorful. Coolest thing we managed to get the flowers growing at was a roof where you could just barely see flowers on the top corner of the building.
