Wanna have an instant Zen garden? Here's a piece of racked sand for you.
Note* this is only a flat piece with racked sand texture to be placed in furniture rooms.

Zen gardens are created with only rock, gravel, sand, and perhaps a few pieces of moss. The dry garden dates back to the Muromachi period, the fifteenth century. Its physical form represents Zen Buddhist philosophy, Zen self-examination, spiritual refinement, and enlightenment. The Zen garden originally was created as an aid to meditation and to teach the principles of the religion.
