Business Card Turing Machine

March 5, 2019

We have something unusual today: a turing machine built from a business card that I learned about on Reddit. I immediately stopped and built my own, and had a lot of fun, and I suspect many of my readers will feel the same way.

Your task is to build your own turing machine. No coding, just playing. Feel free to discuss the exercise in the comments below.

    Very interesting. Based on the Turing Machine emulating a tag system: https://en.wikipedia.org/wiki/Tag_system.
