Ants Drawings

This was an experimental art piece that I made in the south of France on a wall of an Old house. I used the combination of obstacles and diluted muriatic acid to "convince ants to make a picture for me. After many hours of work I was able to get several geometric forms of ant trails. However as I was working on one end of the wall the Ants slowly but surely where starting to diffuse and the geometric figures where slowly going out of focus. Which was kind of cool in it self.
