MIND Breaking: Two GCLs Collide After 29 Years — Napkin-to-Factory Becomes Reality Overnight
MIND Breaking: Two GCLs Collide After 29 Years — Napkin-to-Factory Becomes Reality Overnight
13 November 2025
In an event that reads like scientific déjà-vu, two independently developed languages both named GCL (Geometric Configuration Language) have just merged in production for the first time — and the result is already shipping physical objects around the world.
The 1996 original
Prof. Predrag Janičić (University of Belgrade) and Prof. Pedro Quaresma (University of Coimbra) released GCLC/GCL in 1996 — the world’s first declarative, automatically provable geometric description language. For three decades it has powered geometry education, theorem proving, and thousands of academic papers.
The 2025 reinvention
In October 2025, Jordan Morgan-Griffiths (independent researcher) publicly released his own GCL — built from scratch for reproducible experimental physics. Designed for quantum hardware layouts, DAQ sensor rigs, and defensible science, his version adds hashing, refusal gates, physical units, stiffness/aliasing proofs, and direct Lindbladian export.
They never knew each other existed.
Both chose the identical name.
Both converged on almost identical core syntax.
Both believed geometry should be code, not drawings.
Yesterday, 12 November 2025, a small team quietly connected Jordan’s 2025 GCL to frontier generative AI (Meshy/Luma) and launched SketchPerfect — the first consumer tool that turns any hand-drawn doodle into a photoreal + mathematically perfect + factory-ready 3D object in under 30 seconds.
Early numbers (first 24 hours live):
Yesterday the two timelines finally touched.

Early numbers (first 24 hours live):
- 4 837 objects generated
- 0.29 % print-failure rate (vs ~18 % industry average)
- 180+ countries
- A beautiful textured mesh for show
- A Jordan-GCL+ file that mathematically guarantees flat bases, uniform wall thickness, watertightness, and tolerances — with automated proofs attached.
Yesterday the two timelines finally touched.
