Gravity Drop Physics

Animate [TEXT] with rigid-body physics. Each letter is a chunky rounded-display block with a thick darker extruded edge, colored tomato, mustard, teal or navy in turn. Letters drop one at a time from above the frame with a small random tilt, accelerate under gravity, hit a floor line, bounce slightly, knock into their neighbors and settle a little crooked but readable in a row; then a few small rounded cubes rain down and rest on top. Overlay a physics-notebook look on warm paper: faint grid, dashed collision boxes, short velocity arrows and a tiny time readout. After a short hold, a flat pusher blade slides in from the left and bulldozes the whole pile off the right edge, letters tumbling over each other; then they drop in again. Loop.
