Spinning Daggers

This is hypnotically fascinating.  Benjamin Ducroz has created Spinning Daggers, a series of small wooden zoetrope sculptures composed next to trees during autumn. The sculptures consist of 18 instances - their form is in the shape of different sine and triangle waves modulating over 18 frames. Three of seven models were filmed – you can see the other models along with documentation can be viewed at Ducroz’ website.
