A far more passive diversion than typically frenetic iPad games, Koi Pond puts an impressively realistic, uh, koi pond on your device's screen. Just because the aquatic flora and fauna exist only as pixels doesn't mean they're any less relaxing than the real thing, especially on the iPad's larger, more immersive display.
WIRED Fun options for customizing your pond—plants, stones, sounds.
TIRED No way to browse other users' masterfully crafted ponds or share yours with the virtual koi community.
