For those who have everything
Compared to a pet rock, a marimo moss ball ($14 for six) might strike you as a lively companion. Each small green orb is made of living algae that grows in a sphere, and when cared for, it will grow larger ever so slowly and can live 100 years. Though marimo, or "ball seaweed," grows in lakes throughout the Northern Hemisphere, the Japanese led the way in bringing the balls home and nurturing them. Legend has it that the first marimo balls were the hearts of two star-crossed lovers, and every one since supposedly has the power to discern true love.
