●●SolidEye CandyCozy

Nostalgic image-to-geometry algorithm with satisfying real-time preview, but it's a demo more than a tool.

Strengths

•Accessible browser port removes CLI friction from cult-classic Go tool
•Real-time iterative shape rendering creates engaging visual feedback
•Configurable shape modes (triangles, beziers, circles) let users experiment with different aesthetics

Weaknesses

•No practical output use case beyond visual novelty or artistic inspiration
•Algorithm is unchanged from 2014 original—interesting concept, not novel research

Post Description

I built a browser-based port of fogleman/primitive — a Go CLI tool that approximates images using primitive shapes (triangles, ellipses, beziers, etc.) via a hill-climbing algorithm. The original tool requires building from source and running from the terminal, which isn't exactly accessible. I compiled the core logic to WebAssembly so anyone can drop an image and watch it get reconstructed shape by shape, entirely client-side with no server involved.

Curious if anyone has ideas for shapes or features worth adding.
