Origami-Inspired Sun Protection
FoldRay makes origami-inspired portable gazebos that deploy in 30 seconds, paired with a smart monocle that uses UV-fluorescence to show exactly where sunscreen is applied on your skin.
You look through the monocle at your friend's back and see three glowing red patches they completely missed with sunscreen — one on their shoulder blade, two behind their knees.
You hand them the dragonfruit-scented SPF, they apply, and instantly those spots turn green in the monocle's view. They've never seen their sunscreen coverage before and they're shocked they would have burned.
Green means protected. Red means you'll burn.
