Open, three-tier stage-lighting control with local-first AI calibration.
Design shows in 3D. Calibrate moving heads with a $30 webcam. Run everything from a browser, a phone, or a gyro puck — without the cloud.
A complete lighting-design and control stack that does the jobs grandMA3, Follow-Me, and Zactrack do — on consumer-price hardware that you can actually carry to a basement rig. It ships with:
- 3D show design — arrange fixtures and cameras in a stage model, place spatial effects as objects in 3D space, and watch the preview in real time.
- Moving-head calibration from a webcam — no beacons, no pucks, no wands. Point a USB camera at the stage, hit Calibrate, and every mover knows where to aim within 100 mm at 3 m throw.
- Local-first AI auto-tune — camera exposure / gain / white balance tuned by a vision model running on your own machine via Ollama. No cloud, no API keys, no data leaves the operator.
- Unified mover control — one engine drives DMX from a web slider, a phone's gyroscope, or a wall-mounted ESP32 puck. Claim/release semantics so two operators never fight over the same beam.
- Dynamic shows — the built-in show generator adapts 14 themes to whatever fixtures you actually have, not to a pre-baked preset that demands specific gear.
- Full bilingual documentation — EN + FR user manual, pdf/docx/HTML, with calibration-pipeline appendices (A: cameras, B: moving heads) kept in sync with the code.

- Code map —
CLAUDE.md(project-wide conventions) +docs/ARCHITECTURE.md. - Calibration work — active review series in
docs/mover-calibration-reliability-review.md(appendices A/B in the user manual reference the code line-by-line). - Issues & roadmap — GitHub Issues. Tracker labels for in-flight epics:
mover-calibration-reliability-review-2026-04-23,docs-overhaul-2026-04-24. - Tests — 700+ assertions across 5 Python test suites + 5 Playwright regression suites.
python tests/regression/run_all.pyis the go-to for cross-surface coverage.
