Messin’ around on GitHub.com and searched for “Glowforge.” This showed up: https://github.com/Moirenill/Miranda_Glowforge_Day
I don’t know nuthin’ 'bout code 'n such, but it appears to be something to correct the fisheye on the wide angle lens for the lid camera.
Is the showcases the only way that stuff on that site is at all organized?
