Drawing Machine- Swirly mobile

One of three Drawing machine Mobiles iv designed and have made. The swirly mobile was based one chimes and springs. It's a simple piece. Simply wire shaped into a swirly with a pen at the end. It works in two ways, firstly like a wind chime, hung with the end of the pen resting on paper. As the wing moves the machine it draws freely and without dictation.

 The second way i used it was like a springy pen. I simply tried to write with it. Somthing easy like my name, but with no control over the 'pen' it changes how marks are made.
