David Bayo is a French contemporary artist who creates portraits made up of dots, using a technique called stippling. He starts by drawing out the general layout of his portraits, and then proceeds to fill them up with millions of tiny ink dots.
The video below shows Bayo at work.
At first glance, the two gigantic craters in Didyma, Argolida, Greece, look like the result of a massive meteor striking Earth, but scientists speculate that these craters are actually fallen caves. The caves collapsed thousands of years ago, leaving large crater-like holes.
In the video you can take a look inside the craters. Two small Byzantine chapels with murals that date back to the 13th century are located within the smaller crater.

The Devils Marbles in Davenport, Australia, are large boulders that form the exposed top layer of an extensive and mostly underground granite formation. The natural processes of weathering and erosion have created the various shapes of the boulders. Some of the boulders are naturally but precariously balanced atop one another or on larger rock formations, while others have been split cleanly down the middle by natural forces. The boulders are situated in a wide and shallow desert valley, and are found in scattered groups mainly in the western side of the reserve.
The Devils Marbles are of great cultural and spiritual significance to the traditional Aboriginal owners of the land. Karlu Karlu is the local Aboriginal term for both the rock features and the surrounding area.

Vinegar Valentine, circa 1900 / Public Domain
Vinegar valentines were a type of insulting cards. They are decorated with a caricature, and featured below an insulting poem. Ostensibly given on Valentine’s Day, the caricature and poem is about the “type” that the recipient belongs to—spinster, floozy, dude, scholar, etc. They enjoyed popularity from the 1840s to the 1940s. These cynical, sarcastic, often mean-spirited greeting cards were first produced in America as early as the 1840s. Cheaply made, vinegar valentines were usually printed on one side of a single sheet of paper and cost only a penny.
The unflattering cards reportedly created a stir throughout all social levels, sometimes provoking fisticuffs and arguments. Ironically, the receiver, not the sender, was responsible for the cost of postage up until the 1840s. A person in those days paid for the privilege of being insulted by an often anonymous “admirer.” Millions of vinegar valentines, with verses that insulted a person’s looks, intelligence, or occupation, were sold between the 19th and 20th centuries.

Lava lakes are large volumes of molten lava, usually contained in volcanic craters. These lakes can be formed from one or more vents in a crater that erupts enough lava to partially fill the crater or atop a new vent that erupts lava continuously for a period of several weeks or more and slowly builds a crater progressively higher than the surrounding ground.

Chinsekikan (which means hall of curious rocks) is a museum in Japan that contains nothing but rocks that look like faces. The museum’s founder, who passed away in 2010, collected rocks for over fifty years. Especially strange rocks that naturally resemble celebrities, such as Elvis Presley, movie characters, and more.
