Protocell Division: 2D Vesicle Growth & Excess-Area Fission

2D companion to the 3D protocell-division model: a real population of lipid-vesicle protocells grows membrane area and encapsulated content under a shared, depleting nutrient pool, then splits into two daughters the instant its excess-area ratio crosses a fission threshold — a genuine 2D packed-circle population view with a live nutrient/population/nu strip chart, not a flattened 3D scene.

A minimal synthetic cell — a lipid vesicle enclosing a cell-free expression system — doesn't need genes to divide. This 2D companion to the 3D protocell simulator grows each protocell's membrane area and encapsulated content under a shared, depleting nutrient pool, tracks the excess-area ratio ν between real membrane area and the smallest area a sphere of that volume could have, and splits the vesicle into two daughters the instant ν crosses a fission threshold. The population renders as a real 2D packed-circle scene you can pan and zoom, with a live strip chart tracking population, nutrient level and mean ν over time.
