Mediocre artists put just enough time into their work to finish the job. Truly great artists put their whole heart and soul into what they do, persisting until it's perfect. Some artists keep going well after that point, not stopping when the work is done, or when it's perfect, or indeed ever -- no matter how infuriating and unnecessary the effort might seem. Depending on who you ask, these people either are shining examples of the human endeavor or just, like, really didn't have anything better to do that decade.
Salt Sculptures Built to Be Demolished
You probably think you have the patience of a saint because you waited through that two-hour DMV line and only swore at the clerk three times. But you are nothing compared to Motoi Yamamoto, the artist who makes things like this:
Lairs for his giant spiders. Nothing wrong with that ...
... entirely out of salt.
The salt is not held immobile in any way. Yamamoto makes his creations completely out of loose granules he pours out through a squeeze bottle. Here's a video of him in action, filling a whole room up with his designs inch by painstaking inch. If he sneezed, he'd instantly erase a month of work.
Stefan Worring/Motoi Yamamoto
That's why, after several years, he reluctantly abandoned pepper sculpting.
Yamamoto also defies physics to create 3D sculptures out of the same fine, powdery dust that we can't even manage to wipe completely off the kitchen counter, much less carefully stack into a quarter-scale model of that stairway from The Lord of the Rings.
It comes in pre- and post-earthquake versions. Seriously.
