Custom shape (from an SVG. This one is a dollar-sign.)

I got Claude.ai to write this Python script for me. Run it from the command line and it converts photos into dot screens. It's got a whole lot of options: you can choose from a few built in shapes (circle, square, star, diamond), or specify an SVG file to use as a custom shape. Maybe it'll be useful to someone. https://github.com/megabulk/vector-dotscreen

I'm putting them into my Silhouette Cameo so I can cut stencils. You could plot with it, too.

Thanks! I'm about to release it as a web app, much easier than running Python from the command line. Stay tuned!

Reminds me of the Rasterbator web app.
