Seed Bomb Vending Machine
Seed bombs are little balls of clay, compost, and seeds that you can toss into a vacant lot to try and get some new plants to grow. It's a guerrilla gardening technique and you can see how to make one here
. If you just want to pick one up and live in San Francisco you can now buy them from a vending machine. These were designed by Common Studio from LA and repurpose old gumball machines with the benefits going to Project H Design.
