Plotting machines have been a fascination of mine for a while. I enjoy the process in which digital art is translated to the physical world. This machine is rather unique though. It moves around on 4 wheels giving it a theoretically unlimited drawing area. It can also switch between using sand or spraychalk as a drawing medium. I would love to see a design that was just an evolving pattern as it goes further on rather than a repetitive symbol.

Here is a video of it in action.
