Vociferous Whimsy

ADA - analog interactive installation
A kinetic sculpture by Karina Smigla-Bobinski

From the artist’s website:

Filled up with helium, floating freely in room, a transparent, membrane-like globe, spiked with charcoals that leave marks on the walls, ceilings and floors. Marks which «ADA» produces quite autonomously, although moved by a visitor. The globe obtains aura of liveliness and its black coal traces, the appearance of being a drawing .
