I ve always been interested in little physics sandboxes where you could build things, and was blown away by XKCD s machine a few years ago (https://news.ycombinator.com/item?id=39953514), which is in-turn based on the classic The Incredible Machine . Building tiny machines is fun, so I decided to build an app that let s you build one. It s less geared around moving balls from point A to point B, but is more of a freeform build; whatever you can dream up.Essentially, it let s you build simple machines, mechanisms, and simulations, and watch them play out. There s no practical purpose to it, other than it s fun to tinker, explore, and see what s possible.Try it out, ask questions, and let me know what you think!Live site: https://scribblerig.josnun.com Repo: https://github.com/JosNun/scribblerig
