QR Mosaic

Pick dominoes, marbles or tiles in the Splash tab, then tap to build the code.

A QR code is only dark and light squares, so it can be built from real things. Here dominoes stand on end, and a push sends every row toppling, each domino knocking the next, until they lie flat as the code: ebony over dark modules, ivory over light ones. Or marbles roll in along their rows and settle into the dark modules, or two-sided tiles flip over in a wave.

Every piece is solid and moves as the real thing would. Each build ends on a code that scans, and the splash reads its own last frame to check. Type your own text in the Splash tab.

Made in Splashery. Its code is MIT.

This link opens it in the Playground. To put it on your own page, add the element and one script tag. Every option.
