Jordan Matelsky Has Been Making Holograms — WIth Upcycled CD Cases and a Pen Plotter
Maker and computation neuroscientist Jordan Matelsky has been printing holograms — using a standard two-dimensional pen plotter, a metal stylus, and old CD jewel cases.
"I have a pen-plotter! It's great. It's like having a printer but slow and it breaks more often," Matelsky explains by way of background to the project. "I got it on eBay and it came sorta broken and I immediately spent the difference between what I paid and the price of new one fixing it. Now it's fixed! My favorite thing to do with the pen plotter is to create things that I wouldn't be able to create on, say, a printer, or by hand. Recently, I've gotten excited about using the pen plotter to make holograms."
A hologram is an interference pattern that reflects and diffracts light in such a way as to produce a three-dimensional image — sometimes simply as a form of...
