An interactive game challenges players to time a screen freeze so that only black-and-white patterns are visible, referencing Sol LeWitt's art. The animation cycles through colorful horizontal and vertical stripe groups masked by a face-shaped SVG path. Using the SVG Mask API and `createElementNS`, the code builds layered `<rect>` elements and toggles their visibility via `getComputedStyle` and `setInterval`. A score increments on correct timing, and the timer accelerates after each success, increasing difficulty.
