First piece on the site, so it had to earn the name. The idea: keystrokes as crumbs — input that persists briefly and erodes. Physics is deliberately cheap: one gravity constant, one bounce, and a per-column pile height array instead of real collision. Quantizing x to glyph-width columns makes piles read as piles for the cost of an integer index.

Decay was the hard call. Fading settled glyphs by alpha looked like a screensaver; what worked was eroding piles from the top of each column, oldest-on-top first, so the field visibly forgets in the order it learned. Idle mode types a sentence to itself after a few seconds so first-time visitors see the mechanic before committing a keystroke. Honest limits: no mobile keyboard capture — taps scatter bursts instead.
