Day 9/100: A ball that rolls uphill… or does it? 🎱👀
Gravity Hill, Pittsburgh—terrain optical illusion. Downhill slope appears uphill. Built web map with #MapLibreGL + #MapTiler showing location + video demo of phenomenon.
Experimented with animation: marker rolls onto screen on page load. Small detail, reinforces playful nature.
Reminder: spatial perception isn't just data/measurement—it's context, expectation, sometimes wonder.
Your eyes vs. physics. 👁
