I prototyped everything on my dining room table. I have a long history of missing details so proceeded with the idea that everything needed for the setup (except WiFi and an outlet) would be physically on the table. This made it easy to assure I wouldn’t forget anything.

The booth itself was “programmer art” (the bare minimum to facilitate the task at hand). For printing I used a Polono PL60 thermal label printer because it’s extremely fast and inexpensive to print and there’s no ink to deal with.

Although it lacks color and the resolution prohibits fine shades of gray, a little image processing brought out a few viable styles. I built a script to prepare the images for printing at the push of a button.

Finally, the sales workflow was extremely easy to implement using Google Forms and Google Sheets. We used a Form that my son filled out while interacting with customers. Back at the table the orders appeared on a spreadsheet in which I’d already implemented formulae to format the order for Midjourney (our selected AI image generation tool).
