A Zen sand/rock garden. They are so peacefull and they relax my mind. I got in trouble at school. I went to the store and bought a starter kit. Its a little wodden rectangular shaped box filled with sand. And it comes with 3 minture rocks and a little scraper. Mine took me 8 hours straight and i'm still not done. I will post pics later. I might even buy a little miniture plant for it.
