Hi! 👋 I'm Tyler Robertson
I'm a writer, programmer, and spreadsheet artist.

Here, you'll find all of my weird Google Sheets experiments, created entirely within Sheets's built-in features (meaning there's no Apps Script or Extensions). I hope you enjoy them, and learn a bit about what spreadsheets can do outside of work!

Turing Machine

This is a "Universal" Turing Machine, meaning you can change its function with the punchcard interface at the top of the page. It takes binary input and places it on a "tape" which the machine reads one cell at a time, and processes based on the functions you punch in. The default example is a palindrome checker; if the string is fully removed from the tape, it's a palindrome!
