Embryo Development Simulator: Zygote to Organism (2D)
A fertilised egg divides on a doubling-time model, hollows into a blastocyst, sorts into three germ-layer rings, and elongates into an early body axis — with live cell count and stage timing driving a plain 2D canvas view.
This 2D companion drives the same doubling-time cleavage model as the 3D version through a plain top-down canvas view: a single circle divides into a sunflower-packed disk of cells, hollows into a blastocyst ring, sorts into three concentric germ-layer rings during gastrulation, and stretches into an elongated three-band body axis during neurulation — with a live stage name, cell count and division counter next to the timeline, so the same real doubling-time formula that drives the 3D scene is readable at a glance.
Cell count follows n = min(128, 2^floor(hours/cycleHours)); positions interpolate between a packed disk, a hollow ring, three germ-layer rings and an elongated three-band axis as developmental time advances from day 0 to day 21.
