Paul Rickards does Pen Plotter Designs and sells them in his online shop. If you are not familiar with plotters:

A PEN PLOTTER is an early output device that uses pen and ink to draw directly to paper under computer control. It was the only choice for high quality, color output from a computer from the beginning of the 1950’s through the late 1980’s.

Many were used to create engineering designs, architectural renderings, circuit diagrams, and business presentations. A few found their way into curious computer programmers who used them to design clever designs from programs written on a computer. What they created were the early beginnings of computer based art.

Paul owns over 20 different types of vintage pen plotters. He chooses the plotter that suits the design based on the design, paper type, paper size, plotter speed, and pen types.

The floppy plots are very compelling – you can read more on Twitter and see in Paul’s online shop. There is so much more in the shop here.
