Some of my coworkers and I were talking about our past and the various devices, software, etc… that we used back in school and such, and this came up…
This is a pen plotter:
I used something similar to this in high school. I graduated high school 21 years ago.
It is fascinating to me that the technology of the pen plotter is still being used today, and is seeing a resurgence in all of these maker-devices from 3d printers to Silhouette Cameo to our very own Glowforge.
I suppose the pen plotter technology never really went away, it just shifted to the industrial/manufacturing industry and is now being miniaturized as more people want these devices in their homes.
