Potholes are an unsightly annoyance, and Paris, like many cities, has a lot of them. Instead of waiting for the bureaucratic powers that be to get around to fixing Paris's streets, Juliana Santacruz Herrera took revitalization into her own hands with her projet nid de poule (pothole project). Rather than use boring—yet admittedly reliable—cement, she opted for colorful yarn to fill the cracked streets. We're not sure how it will stand up to wear and tear, but it sure makes the streets look pretty.
