... 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.

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.

We can't imagine putting half the amount of effort into raising a child, much less a tiny salt maze ...

Motoi Yamamoto
He makes slugs solve this maze. If they touch the walls, they die.

... that will be utterly destroyed after only a few weeks. Yamamoto doesn't just invite the audience to completely annihilate his artwork -- he insists that they tromp through his delicate lines like a bunch of well-seasoned Godzillas.

Again, this only makes sense if he's marinating victims for his giant spider pet.

He only asks that, after these heathens are done ruining something beautiful, the salt be returned to the sea from whence it came. Salt is very important in Japanese culture, as it's used to purify bodies after death and ward away evil spirits. That's why Yamamoto does this: All of his work is dedicated to his younger sister, who died of brain cancer in 1996.

Great. And we promised we wouldn't cry today. Maybe Yamamoto can use our salty tears to paint a forest or something.

That's how the memorial appears from satellite via Google Earth. We hope you appreciate it, because you are essentially its only audience. It's not like scorpions and buzzards are known for their fine artistic sensibilities -- no swooning art lovers are going to wander by this work with a glass of wine. Two full months of sweaty, back-breaking work in the Saharan summer, and it was all solely for the benefit of the families themselves, and probably also to really confuse armchair Internet explorers.

"We still get emails from puzzled Lost fans."

Imagine dedicating your entire day to putting together a huge work of art with painstaking precision. Sure, it's only a single day, but it's exhausting work, and the results are impressive. Then, as soon as it's done, you turn around to watch the tide wipe it all away. We punched a crab once when the sea filled in a moderately deep hole we'd managed to dig. We can't imagine the heartbreak of watching something like this erased like God's Etch A Sketch:

Another classic Beach Boys recording lost forever.

The guy on the right is Jim Denevan, and he spent all day doing this with a rake:

Jim Denevan
"It's no use, Jim. You'll never get it clean."

Denevan doesn't use any kind of measuring device or schematics to form his art; he just has an uncanny eye for what it looks like from the sky. And after his work is done, he's lucky if somebody manages to snap a hasty photo or two before the work is inevitably reclaimed by the sea. When asked how he feels about dying a little bit inside every single evening, he replied: "Who would want it not to wash away?"

Jim Denevan
Why does he want to erase this? Who is he contacting?

We're not sure if that's a beautiful sentiment about the fleeting nature of life, or if Jim is just a bit of a masochist.

Observe the corny shenanigans of Brett Herbst:

The MAiZE
See: You really do need cursive when you grow up.

This particular work holds the world record for the largest corn maze, clocking in at just over 12 acres. That is an entirely different breed of labyrinth from the wimpy little Halloween corn mazes of our youth. A 12-acre corn maze might actually have a literal minotaur at the center, waiting to battle all those who find him. How would we ever prove otherwise? By walking 12 acres? Not bloody likely.

You can see from that first photo that Herbst has a thing for science fiction. Here's his Star Wars-theme maze, which, despite being agriculture, is still a better prequel than Phantom Menace.

Smith Rock Ranch
It's dedicated to Maize Windu.

Herbst is a little secretive about the exact method he uses to create his mazes nowadays, because his success has spawned a few large-scale corn maze copycats (food labyrinths are apparently a booming industry). But he does reveal that, initially, all of his mazes were carved out by hand with a weed whacker.

"It takes a strong set of arms to get through this much whacking."

Probably makes you feel like a bit of a dick for complaining about the weekend yard work.

If you were flying over Belfast last year, you might have spotted a gargantuan child's face staring back at you from the ground.

Or a face flying through the air and closing in on you.

After quietly closing the window, downing the rest of your scotch, and trying not to go all William Shatner on the flight staff, you may have brought up Google and found that it was a piece by Cuban-American artist Jorge Rodriguez-Gerada called "WISH."

And also that it was way, way bigger than you could have imagined. You get the idea from that photo that maybe it's the size of a small parking lot or something. Here's what it looked like from the ground:

Ulster Bank/Belfast Festival at Queens
"Yo, your penguin sucks."

Yes, that tiny dot at the bottom right is a man standing beside construction equipment. "WISH" spanned 11 acres, took 18 months to complete, and was built out of 2,000 tons of sand and 2,000 tons of soil. Imagine trying to plan something that immense, toiling away at it every day for a year and a half when, at the artist's level, all you see is this:

Jorge Rodriguez-Gerada
It's a fulfilling job, if you like dirt, and lines.

More unbelievable is that most people in Belfast couldn't possibly appreciate Rodriguez-Gerada's effort, because there was no point in the city high enough to see it from. The artwork could only be viewed by an aircraft, a government drone camera, or a vacationing Superman.

Ulster Bank/Belfast Festival at Queens
All three would battle over it, and the artwork would be destroyed.

This wasn't Rodriguez-Gerada's first attempt at creating artwork exclusively for low-flying aliens. Here's one of his previous works, a portrait of Barack Obama on a beach in Barcelona:

This one took 650 metric tons of sand and gravel. Here they are applying it by hand with small shovels:

By contrast: On more than one occasion, we've bitten into a Snickers wrapper because our hands were slippery and we couldn't wait long enough to get it open the normal way.

It was called "Wrapped Coast" and involved gift-wrapping 1 million square feet of Australian coastline in fabric. The piece was larger than Mount Rushmore -- so large, in fact, that it could not be viewed in its entirety from any one vantage point. Clearly these are the actions of some small army run by an insane person. Cobra Commander is our first guess. But no, Wrapped Coast was the result of artist Christo and his wife Jeanne-Claude's relentless appetite for covering things in other things. They've gift-wrapped the Pont Neuf Bridge in Paris:

It's also technically the world's biggest dental dam.

The Reichstag in Germany:

And even these entire friggin' islands in Florida:

We're not sure what statement they're trying to make by gift-wrapping large chunks of the planet, but Galactus: Devourer of Worlds is probably going to be pleasantly surprised when he gets here.
