Flow Fish

Three koi swim through waters made of words. Toss a character, and they race to devour it; extend your palm, and the school gathers - a living pond of algorithmic calligraphy.

About This Work

Fish are the freest image in ink painting. Flow Fish lets three digital koi roam screen waters - each with its own personality, swimming posture, and glow temperature. They know to avoid obstacles, school together, and chase food. And the food is characters. Tap the surface to drop a word, and the fish swarm like they've caught the scent. Long-press, and words orbit the fish body like planets around a sun. Turn on the camera, and the school follows your palm across the screen. You are creator and keeper.
