# Visual Lineage

*A 23andMe for imagined instruments.*

Blend culturally-sourced instrument LoRAs trained on **FLUX.2 klein (4B)**, generate hybrid instrument images with full provenance tracking, and convert them to 3D meshes for printing.

## How it works

1. **Harvest** — We source legally-clear (CC0/CC-BY/Public domain) images of culturally specific instruments from Wikimedia Commons and Openverse.
2. **Train LoRAs** — Each instrument gets its own LoRA (350MB) trained on FLUX.2 klein via **Modal** (A10G GPU).
3. **Compose** — In this Gradio app, pick any two instruments, set a blend ratio, and describe your imagined hybrid.
4. **Prove ancestry** — Every generation shows a provenance record: which LoRAs were blended, at what weights, with what prompt and seed.
5. **Convert to 3D** — Download the image and use the included ComfyUI workflows (Tripo API / TripoSR) to generate a 3D mesh for CAD → 3D printing.

## ComfyUI 3D Workflows

Located in `comfy_workflows/` of the repo:
- `tripo_api_image_to_3d.json` — Tripo cloud API (bring your own API key)
- `triposr_image_to_3d.json` — Local TripoSR (experimental, requires full VAE)

## Build Small Hackathon

This project was built for the [Build Small](https://build-small-hackathon-field-guide.hf.space) hackathon (June 2026).

**Track:** Backyard AI — practical, problem-solving apps built to improve daily life.

**What it does:** Allows musicians, instrument makers, and tinkerers to visually explore hybrid instrument designs by blending the visual DNA of culturally significant instruments, then export those designs toward 3D printing — bridging AI generation with physical fabrication.

**Sustainability:** Each LoRA is only 350MB. The base model (FLUX.2 klein at 4B parameters) runs well on consumer GPUs. The entire pipeline from dataset harvest to training to inference uses open-source tools and runs on accessible hardware.
