PolskiIbis Mudflat Probe Lab — 2D Tactile Foraging
A top-down 2D companion to the 3D ibis scene: wading birds sweep exposed mud, probing with a long bill for invertebrates buried at random depths — a capture depends on whether the bill's reach exceeds the prey's burial depth, while the tide exposes and re-floods patches and drains energy from birds wading through deep water.
This 2D companion rebuilds the 3D ibis scene's mudflat as a readable overhead map with a real tactile-probing model underneath it: dozens of mud patches each hide an invertebrate colony at a randomly drawn burial depth, and a capture only happens when the bill-depth slider reaches deep enough — the catch probability follows 1 − e^(−probe depth / prey depth), so shallow-buried patches pay off at low probe depths while deep colonies need a longer bill reach. A slow tidal cycle raises and lowers the water line, submerging low-lying patches (birds can't probe underwater, and wading through what's left drains energy faster) while exposing higher mud for foraging; submerged patches also regenerate their stock faster, modelling tidal recruitment of new prey. A live panel tracks total contacts, the flock's average energy, a rolling capture rate and the current fraction of exposed mud.
2D top-down ibis probing lab: exponentially-distributed prey burial depth per patch, a 1 − e^(−depth/prey depth) capture-probability formula scaled by remaining patch stock, a slider-driven tide level with a slow sinusoidal swell that submerges and re-exposes patches, water-depth-scaled energy drain and speed penalty, and a live contacts/energy/capture-rate/exposed-mud readout panel.
