Since the first of January 2015 I started making a visual study of a little stone everyday in a 14×14 cm sketchbook. Each one of these studies takes a different model, procedure or visual language, so I allows me to explore different ways of representation (graphical/pictorial), and also the boundaries of what we define under the same category (a small and common object in this case).
This is an ongoing project that will end at the end of the year, having completed the same amount of studies that days of one year.
Love your rocks! They are so cool!!
