Krill Keeper: Virtual Pet Tank

A single krill drifts into your tank.

Feed it, keep the water clean, and it grows. Eggs hatch, new friends arrive, and before long your krill start swimming together as a swarm.

[Just watch them swim]
The swarm is not a canned animation. Every krill reacts to its neighbors in real time, gathering, turning and scattering. Put on the calm deep-sea music and let your mind drift. It is a quiet place to rest for a minute.
