A fair comparison.
KEEP THE QUESTION. SHARE THE EXPERIMENT.
Save your comparison.
Settings links/files restart the experiments. Full snapshots preserve both active simulations, painted fields, timing, brush positions, and graph history; opening one resumes from that moment, paused. Copy snapshot link stores an immutable copy on PopFun and creates a short link. Anyone with that link can open it. Browser space is limited; downloaded snapshot files remain available as backups.
A starts with low viscosity; B starts with high viscosity. Choose a model and experiment in each panel, then adjust its sliders. Reset both restarts their experiments with their current settings. Copying A’s setup restarts both. Linked brush inputs use the same position and gesture with each panel’s own brush settings.
Swipe horizontally inside the comparison to see both panels.

Simulation B

Both panels advance one fixed simulation step per shared tick. Different models use normalized units, so equal step counts are not equal physical time across models. Both ready panels advance while this page is visible; slower devices run more slowly. Each panel can also be reset independently. Live simulation state lasts until this page is reloaded. Save settings for a fresh experiment, or save/download a full snapshot to resume the current moment. Snapshots cover the two active models; inactive model history is not included.
