Greenaid is an unconventional design project that provides seed bombs from converted gumball machines. The seed bombs are composed of clay, compost, and wildflower seeds and are meant to be dropped in abandoned lots, sidewalk cracks, or anywhere else that needs a bit of natural greenery. A donation of $10 to their Kickstarter campaign will get you a package of your own seed bombs and will help to bring more of the vending machines to the Los Angeles area. If you contribute $650, you can even get your own machine to deploy in your community. Fantastic idea!
