August: brighten your summer doldrums with these special sites.

If the words "bruk up" and "flexing" don't sound familiar, you might want to read, and watch, this New Yorker article on street dancing in Brooklyn, New York. Expressive doesn't begin to describe what is happening, and you don't need to buy tickets to see these amazing bodies.

Last month we linked you to a retrospective of the sculpture of Barbara Hepworth at Tate Britain. We follow up this month with an article from the Telegraph on how Hepworth's art "changed the face of sculpture". Jeanette Winterson tells us that Hepworth believed in art as a human necessity, an expression of the soul dating back to ancient times. Sculpture, she felt, belonged outdoors, not as a luxury but as a tribute to humanity's unending battle for survival.

A treasure trove of artefacts from the ancient Mayan civilization has been unearthed in Guatemala. Three stone panels, beautifully preserved, are covered with hieroglyphs that give additional insights into this complex civilization.

It appears that Zaha Hadid's elegant design for an olympic stadium in Tokyo has been cancelled. The building was planned to host the 2019 rugby world cup, followed by the 2020 olympic games. The ostensible reason given is that the project ran far over budget. Readers of this column will remember that scorn was heaped on the design because it was said to resemble a vagina. Japanese architects seemed particularly incensed: one commentator described the stadium as "a dull slow form, like a turtle waiting for Japan to sink so that it can swim away".

Web Urbanist treats us to some bits of architectural fancy with delightful structures that will never be built. These renderings tickle the eye and suggest possibilities for the creative mind to explore.

Grab a latte, settle back, and immerse yourself in this article from Commentary Magazine titled "How Art Became Irrelevant". You will get a brilliant overview of contemporary art trends, from Chris Burden's shooting to auction houses, from Karen Finley's chocolate body smears, through the attempted defunding of the NEA, Andres Serrano's "Piss Christ", Susan Sontag's thoughtful essays, Christian ideology, and architectural irreverance. Michael J. Lewis leads us through a brilliant tour of what art seems to be saying, and you don't have to pay tuition to be treated to it. Outstanding!

Look at our cover image this month, and then look at these photos from the New York Times of Cuba's coral reefs. It is eerie to think of the correspondences, although the cover image was created long before I saw this article. The video says, "you will see things you will never see anywhere else". That could well describe what digital artists today are envisioning.

Agnes Martin may have struggled with schizophrenia, but she has attracted a devoted following. Tate Modern offers a retrospective that attempts to understand the aesthetic rigors and tight meshes that fill her work. The Tate describes Martin's work as an "attempt to plot her universe and to keep the chaos of her consciousness together", but they also see a transcendant light that shines through the dangers of our contemporary existence. The exhibition presents over 100 works in a dozen rooms, arranged mainly chronologically. Martin died 11 years ago - this is the first major retrospective of her oeuvre.

The BBC asked its readers to select their favorite works by the Austrian symbolist painter Gustav Klimt. Whether you agree with the choices or not, you will find a rare opportunity to see some of Klimt's finest works together, from "The Water Serpent" to "Portrait of a Girl with Bended Head".

A controversy between an artist and a gallerist has resulted in an unusual decision by a judicial court in the Netherlands. Artist Danh Vo has been ordered to produce a "large and impressive new work" for an art collector, with the collector to give "mandatory input" into the piece. The work has to be produced by June of 2016. The decision has been denounced as "absurd", and a "serious threat to the intellectual freedom of creative individuals everywhere".

Those of you who enjoy unusual architecture will want to look at this concept for a cliff house overlooking the Aegean Sea. Called "Casa Brutale", the renderings show a severe, uncluttered habitation in the strictest minimalist fashion with intriguing vistas for the eye. The engineering involved, should it ever get built, would be a monumnetal challenge, but the concept is certainly bold.

Described as Titian's most erotic masterpiece, the canvas once denounced as a fake now is treasured as priceless. The tease line of this article about the background of the painting speaks of a Cardinal, a prostitute, and a painter. Read about this voluptuous body, the shower of gold representing her lover Zeus, and the command to produce an exceptionally erotic nod to love.

Again from the Guardian, we are treated to a fascinating description of the life of composer Eric Satie. According to this account, Satie was indeed an individualist: he established a one-man religious sect; he once bought seven identical gray velvet corduroy suits; he ate an omelette made from 30 eggs; and he lived in dreadful squalor. Satie wanted to destroy rules in musical composition, to combine the surreal and the absurd, to erase boundaries between so-called high and low music. The presentation on Satie was titled "Memoirs of a Pear-Shaped Life" and was shown at the Parabola Arts Centre as part of their music festival.

Last month we had our first visitors from Cameroon, reminding me of the strength and beauty of their art. I used to collect these stunning pieces, so it is a pleasure to point you to some of their masks as well as their sculpture. Note that the sculptures come from the grasslands of the western part of the country: the north is under Islamic rule and thus no sculptures are allowed.

Here are the best images I have seen so far of the surface of Pluto and the details are stunning. We also learn something about the atmosphere surrounding Pluto's largest moon, Charon. NASA's excitment about their findings is palpable.
