Developer tristanbob completed a 72-hour Gauntlet Loop: building a 3D university campus from scratch with Cursor. The Gauntlet Loop format, proposed by Matt Shumer, is an intense time-boxed sprint where you pair-program with AI and ship a complete project.

He published a video retrospective on how well it went — where AI coding visibly accelerated the work, where it fell short, and what the time-boxed high-pressure workflow actually feels like. Useful for anyone curious about AI coding tools' real output on a large 3D project.
