Hikaru Dorodango

Apparently, in Japan, there's been a revival of hikaru dorodango. Essentially, the goal is to make a sphere of mud. The end result look like a small bowling ball, sans the holes. It lusters after being polished.

Perhaps the appeal comes from the fact that it takes some time to master the skill of making these mud balls, and yet the final result makes you wonder if they are indeed made of mud to begin with. The result is far more serene and beautiful than one might expect.

Have a look.
