Beautifying the city with an anarchic touch! This is a concept that combines street art with guerrilla gardening. When the ball is thrown it breaks upon impact, splashing colourful paint in the shape of a flower. Inside it seeds are nestled in clay, that over time, grow into wall-mounted plants. (It goes without saying that it consists only of biodegradable materials.) Urban Ivy allows the nature-loving, concrete-hating user to make his or her mark.
