Show your work-in-progress

Rolling thread for stuff you're building — half-finished is welcome, that's the point. Post a screenshot or a gif, say what it is and what you're stuck on. Early feedback beats polishing in private for three weeks and finding out the core loop isn't fun. If you're using the editor and .j17 scripting, feel free to paste a snippet you're wrestling with — someone here has probably hit the same thing.
