You know, I was once asked by someone why always spheres and round shapes, why never any cubes and boxes?
This was actually not entirely true, but true enough, as it referred to my paintings from a certain period (of several consecutive years). That question inspired me to a drawing, however my state of mind while drawing was, albeit somewhat curious, also quite disinterested. It was rather a "There you go! A box! Now back to..."
How often does nature create boxes?
