A satin walnut cube tumbles toward the lower right across a wooden chessboard floor, with creamy boxwood and deep chocolate-brown squares inspired by fine chess sets. Seven wooden cubes arrive from different directions, roll into place and climb onto the base to make a perfect 2 × 2 × 2 cube. Their grain lines up into one continuous wooden surface. The completed cube makes four more rolls in the same direction as the camera pulls back, arriving on a matching section of floor before the loop begins again.

Open Grow Cube on a display, or select Grow Cube from the RCWeb controller's Apps list. The animation starts automatically and repeats every 18.65 seconds. There are no playback controls or player limits.
Scan the bottom-right QR code to open the standard RCWeb controller in the same room. Use its Apps list to switch the display to another app. Grow Cube does not need a separate controller, and each display plays its own loop.
JavaScript and hardware-accelerated WebGL are required. WebGL 1 browsers are supported, including devices with lower shader precision. The floor uses fixed square tiles to keep its pattern reliable on older graphics hardware. A compatibility warning appears if graphics cannot start. The room QR panel remains available so you can switch to another app.
