Drink water, reveal ukiyo-e. Classic Japanese woodblock prints by Hokusai — each layer unlocked by your daily hydration progress. More paintings coming soon. Hydro Paint turns daily hydration into a quiet ritual with art. Each day starts with a blank canvas. As you drink, layers of a classic ukiyo-e painting are gradually revealed. Tilt your phone and the painting responds with parallax and light. Tap the card and it sways. Reach your goal and the full artwork comes alive with a celebration. Currently featuring three interactive paintings from Hokusai's "Thirty-six Views of Mount Fuji," with more works by Hiroshige, Koitsu, and others on the way.
