Smart Pill 2D: Distance-Tracked Peristaltic Transport & RF Telemetry

The 3D smart-pill simulator moves its capsule along a coiled 3D tube at a constant visual pace, with elapsed hours displayed only as a decorative label. This 2D counterpart is built the other way around: the capsule's centimetre position along the GI tract is the quantity actually being integrated, one segment at a time, using each segment's real average length and residence time — so the pill visibly crawls through 2 hours of gastric mixing and 20 hours of colonic transit in correct proportion to the seconds it races through the esophagus and duodenum. A schematic 2D torso cross-section renders that position live, RF received signal strength is computed from the capsule's actual distance to the torso boundary rather than a lookup table, and a scrolling telemetry strip plots pH, signal strength and drug release as independent time series so the same physics can be read two different ways at once.
