This is a great find by my friend Maggie. Two-thousand LED paving stones have been set in amongst the cobbles on the Place du Molard in Geneva. What a magical place!

These lit pavers disrupt our expectations in so many subtle ways. We are so used to light coming from above that lights from below seem to upend the world in a beautiful way. We also expect solidity and density from the stones under our feet, not translucency. And every day, there is the renewed joy of dusk — watching certain stones defy the graying landscape and come to life.
