App 2.50.0: the Caterpillar crawls while you drive

Browse Source 
A hump runs from the tail to the head, lifted feet swing forward while
the others stay planted, and the branch it walks on slides by with the
speed. Parked, it settles into its high arch.

- 2026-11-07 — App 2.50.0: **the Caterpillar crawls** (owner: "make it so the caterpillar appears to be going when we drive? Using normal caterpillar movement?"). While the car moves it crawls as a caterpillar does: a hump runs from the tail to the head, the body bunches and stretches a little, feet that are lifted swing forward and the others stay planted on a branch whose knots and leaves slide backwards with the speed; the crawl is quicker the faster the car goes (at most 1.2 crawls a second). It does not change its place on screen, so the readings stay put. Parked, it eases back into its high arch (it keeps drawing for that moment only). Two screenshots redone. Tested: unit tests, lint, emulator with sample values (frames 0.25 s apart show the hump travelling and the branch sliding). Not tried on the car.

- 2026-11-07 — App 2.49.1: **the Caterpillar looks more like the one in the book** (owner: "Make it more like the original caterpillar", with the German edition's cover as the reference). It arches over the middle like the cover's: overlapping chunks of mottled green and teal paper, a yellow fringe along the back, olive feet, and a red-orange head with a yellow face, green eyes and purple antennae; the speed is on the face. Power still lights the segments (blue when regenerating) and the back humps while driving. Still my own drawing of it, not the book's artwork. Two screenshots redone. Tested: unit tests, lint, emulator with sample values. Not tried on the car.
