There is a lot of research and art on humans using computational creativity tools, but in RoboAction A1 K1 by Dragan Ilic, a Kuka robot uses a human as a tool, though the only job the human has is to hold some paintbrushes.
Whilst it is hard to miss the robot in this spectacular performance, it is a bit less interesting from a robot creativity point of view. The painting pattern is deterministic and pre-programmed, and without the human in the loop the result would have been exactly the same.
