Good morning, Kirk. If you picked a time and place for Harmonia's five minutes last night, keep it today, with your phone face-down. If you didn't get to it, choose one now. When it's over, say or write one word for how it felt.

Six things most people miss:
- Ant trails work partly because the scent fades. Short routes get walked and marked again faster, so they stay strong while stale ones disappear. On the mesh, route scores could fade too unless fresh traffic keeps renewing them.
- Concert pitch keeps creeping up. Baroque players often tuned A near 415, today's standard is 440, and some orchestras go to 442 or 443 because brighter sounds more exciting.
- In any big city, at least two people have exactly the same number of hairs on their heads, because there are more people than possible hair counts. In the same way, any fixed-length ID will eventually collide, so it's worth keeping a ledger entry beside it.
- Making a choice takes longer the more options there are, but only slowly, and grouping them cuts the time further. That's why the More room's six labeled groups beat one long list.
- Curb cuts were built for wheelchairs, and now strollers, bikes and suitcases use them every day. When you design for the kid who can't pay even a dollar, the low-energy version usually helps everyone.
- Wet pavement looks darker because water smooths the rough surface. Light then bounces around inside the water and gets absorbed instead of scattering back to your eye.

Glow eternal. 💙
