Smart floor tiles with embedded LEDs that create flowing light 'rivers' through your home. Your NFC phone guides you with gentle flowing paths to the bathroom at night, kitchen in the morning.
You wake at 3am to use the bathroom. As your feet touch the floor, a soft blue light river silently flows from your bedside, guiding you through the dark hallway without waking your partner. It's like walking on water - pure magic that feels both ancient and impossibly futuristic.
