tl;dr: A developer built a Chrome extension that gradually covers neglected browser tabs with animated vines and plants, blocking interaction once overgrowth exceeds 5%. Users must slash through the overlay with a machete, chainsaw, or flamethrower to regain access, with configurable timing for how quickly tabs become overgrown. The code is split into a background worker, popup UI, and content script handling the SVG overlays and neglect timer.
