These Drawings,

may look like they were made using  Spirograph gears,

 but they are not, they were made by this fantastical machine below,

an inventive machine by musician Lamond Campbell, adds a musical component to its looped sketches, The Harmonograph Synthesiser is exactly as its name suggests: Campbell connected a modern, modular synthesizer to an 18th-Century harmonograph, an antiquated apparatus that uses pendulums to render geometric shapes,

two of the swinging mechanisms move linearly with the pen, while the third rotates with the board. Each triggers the synthesizer when movement occurs, which creates the corresponding audio track. An additional microphone picks up the noise of the pen, if you watch the video above you will see the intricacies of the modified contraption, Campell is selling a complete, 18-track collection on his site, and you can find more about his multi-media creations on Instagram and YouTube, what an amazing machine!
