String Art Workshop
Make a circular string portrait with measured nail positions and a numbered path you can follow at your own pace.
How we build a check
This workbench processes supported inputs locally. We test calculations, file structure and generated artifacts using independent readers or known fixtures where available. The example runs the same processing path as a supplied input; it does not stand in for checking your own result.
