Sumi - Japanese ink landscapes, quietly alive on your desk

Five sumi-e ink landscapes that move — a waterfall, rain on a pavilion, moonlit bamboo, waves, koi. They shift with the hour, make their own sound (synthesised on-device, no audio files), and fall asleep on a timer. No ads, no tracking, no subscription. $5.99 once, including every painting added later.
