RCWeb Block Clock
Block Clock is a display-only RCWeb app that shows the current local time as colorful Tetris-style blocks.

The clock appears at the top of the screen in HH:mm:ss format. When a digit changes, the previous digit is released as one connected Box2D rigid body made from block fixtures and falls onto the shared floor at the bottom of the display. The replacement digit fades back in after a short delay, while the colons stay fixed in place.
When the pile grows too high, the next released digit becomes an exploding digit. It detonates near the pile, applies outward Box2D impulses to the other fallen digit bodies, and breaks into its component block bodies.
