Artificial Life — scientific sources and attribution (rebuilt September 2026) Gemina: Hydrogeminium natans, Bert Chan (MIT). https://chakazul.github.io/lenia.html Specimen and parameters: Chakazul/Lenia/Python/animals.json, commit adfc542939266de7f4bb7ebb552e8499701ee107 (code 3GH2n). The original record is retained in gemina-specimen.json; MIT notice below. Four independent periodic 128x128 cultures, polynomial kernel/growth. R=18, beta=(1/2,1,2/3), mu=.26, sigma=.036, dt=.1. The four specimens are independently prepared for 0, 90, 180 and 270 steps, then recentered and rotated by integer quarter-turns without density resampling. All four numerical channels evolve independently, with zero inter-channel coupling. Their actual unwrapped centroid displacement is used to compose a 256x256 periodic observation field. They are not repeated display copies and their motion is not a prescribed path. Overlap in this observation field does not imply a physical interaction between the separate cultures. The published parameters and lattice spacing are unchanged. The model clock starts after preparation; eight equilibration steps count in it. The target is 42 steps per active second in focus, reduced in the overview. The observer starts fixed; optional camera rotation affects presentation only. No forced movement, respawn or artificial steering is applied. Gemina uses FFT convolution in a background worker (CPU compatibility fallback), not the much larger direct WebGPU convolution used by the previous shared field. Pelagic: an independent browser implementation of the published Particle Lenia equations and 3D parameters, Alexander Mordvintsev, Eyvind Niklasson, Ettore Randazzo (2022). https://google-research.github.io/self-organising-systems/particle-lenia/ 256 particles; normalized spherical kernel, local energy gradient, Euler dt=0.2. Seeded spherical distribution with minimum initial spacing differs from the JAX notebook; no exact trajectory or biological realism is claimed. Particle positions are genuinely 3D. Mitosis and Corallium: an independent implementation of the Gray–Scott equations and the mitosis/coral parameter studies described by Karl Sims. https://www.karlsims.com/rd.html The model uses a periodic 192x192 field, a nine-point diffusion stencil and dt=1. Asymmetric, separated seeds improve visibility and stagger the initial growth. 160 initial equilibration steps count toward the displayed model time. The spatial discretization and documented reaction parameters are unchanged. Only the equations and parameter values are used; no Sims images, video or code are redistributed. Titles and visualization design are by Kling Labs. Lenia and Gray–Scott are 2D models visualized directly across the image. Catmull–Rom reconstructed concentration gradients and colors are illustration, not additional biological measurements. There is no microscope, plate or aperture. Initial equilibration steps are counted in displayed simulation time. Model units are dimensionless. Independent WGSL compute shaders execute the Particle Lenia and Gray-Scott models using WebGPU when available in focus mode. A pure JavaScript worker is their fallback and Gemina's primary compute path. The direct renderer uses shaded fields and projected 3D particles, with a Canvas2D compatibility path. Display interpolation does not feed back into model state. Particle membrane/nucleus appearance is illustrative; green tint encodes measured speed, core intensity counts neighbours within 2.2 model units. Three observation modes: shaded form, unlit concentration (or particle neighbour density), and activity. Field activity is the difference between consecutive states divided by their model-time interval; positive is mint and negative coral. It includes transport as well as growth. Contrast uses 1-exp(-abs(rate)*s), s=6 for Lenia and s=350 for Gray-Scott, so colours are not inter-model comparisons. Particle speed is mapped with 1-exp(-speed*18). Readouts are the mean absolute field rate or mean particle displacement speed, without this colour mapping. Observation, interpolation, panning and independent camera pause do not feed back into any numerical state or change the model equations. No pretrained AI or personal data are used. Retained Lenia numerical core and specimen attribution: Browser implementation of StandardLenia and ExpandedLenia as described by BirdbrainEngineer/lenia_ca (MIT), commit ee7b79b09334928a25dbcc96edc33edd57362724. The Orbium seed is decoded from images/glider.png in that repository. https://github.com/BirdbrainEngineer/lenia_ca Three additional specimen patterns and parameters are by Bert Chan (MIT), from Chakazul/Lenia/Python/animals.json, commit adfc542939266de7f4bb7ebb552e8499701ee107. https://github.com/Chakazul/Lenia This is a JavaScript browser implementation, not the Rust crate running in WASM. Gemina is the only active Lenia specimen, stored in its own pinned data file. The retained multichannel and specimen routines are not additional scenes.
