What you need:
A good large base canvas. (One on the pavement, preferably).
A sweet substance. (preferably with a control spout. I.e. honey, Chocolate syrup).
A shitload of ants. (preferably the friendly kind.)
we all have experienced this very familar phenomenon take place on the sidewalk, in the corner of a high school hallway, and in some cases your bedroom. A piece of food is dropped, and within minutes it becomes saturated with eager ants. This little spectacle of nature is what inspired Bio Graff.
Think of a really important message, one you want to tell everyone. Take your sweet substance and draw that message upon the pavement. Within moments this message will become live with thousands of little ants clammering for a piece of that sweet, sweet message.
