New in the Adafruit Learning System today: the Tiny Autostereogram Construction Kit

What is an autostereogram?

There was a buzz created in the 1990s when the series of “Magic Eye” books were first published. These books displayed 3D images on plain paper without the need of any special head gear like red-green, Polaroid or LCD shutter glasses. These 3D images could be seen with the naked eye.

The secret was the use of a horizontal repeating series of dots with a slight variation in the repeating series to give the illusion of depth in the 2D image. These images have been called a few names, including autostereograms, single image random dot stereograms (SIRDS), and single image stereograms (SIS). We will call them autostereograms in this learning guide.

With the Tiny Autostereogram Construction Kit (or TACK for short), you can create your own autostereograms using CircuitPython and an Adafruit Metro M4 Express and an Adafruit ePaper shield. It creates these 3D images from black and white or grayscale BMP images and display them on an Adafruit ePaper shield. You can even save them to a file and post them on social media.
