I wrote a little utility to simplify the process of creating and printing the images to customize the finale of a routine involving tic tac toe.
I've spoken with a number of performers who have difficulty printing the images, so I decided to make my utility publicly available. I updated it to be easier to use, work in more browsers, and support all sizes of the prop.
I’ve made it available on GitHub under the open source MIT license, meaning anyone can freely use, copy, or modify it.
You can use it at https://magicalbrad.github.io/tictactoe/
