The Bloomsbury group’s habit of non-binary bed-hopping has frequently attracted more attention than the artworks they produced. But in their Vanessa Bell retrospective, the MK Gallery has steered blissfully clear of salacious tittle tattle. Thankfully, this allows one to focus on Bell’s paintings and designs rather than her complicated domestic life.

Brazilian artist Lygia Clark is best known for taking her abstract sculptures off the pedestal and inviting people to interact with them. Dozens of constructions named Bichos (Beasts or Critters) (pictured below right) are hinged along the joins to allow you to rearrange the parts in seemingly endless configurations.

Like an angry teenager rejecting everything his parents stand for, American artist Mike Kelley embraced everything most despised by the art world – from popular culture to crafts, and occultism to catholicism – to create what he ironically called “blue collar minimalism”. “An adolescent,” he declared, “is a dysfunctional adult and art is a dysfunctional reality”.

In September 1899, Claude Monet booked into a room at the Savoy Hotel. From there he had a good view of Waterloo Bridge and the south bank beyond. Setting up his easel on a balcony, he began a series of paintings of the river and the buildings on its banks. So entranced was he by the river that, over the next three years, he came back twice to continue working on a series that would mushroom to over 100 canvases.

Michael Craig-Martin was the most playful and provocative of the conceptual artists. His early sculptures are like visual puns, a play on the laws of nature. On the Table, 1970 (pictured below right), for instance, appears to defy gravity. Four buckets filled with water stand on a table; so far so ordinary. But the table has no legs and is suspended from the ceiling by ropes and pulleys.

Van Gogh: Poets & Lovers includes many of his best known pictures and, amazingly, it is the first exhibition the National Gallery has devoted to this much loved artist. Focusing mainly on paintings and drawings made in the two years he lived in Provence (1888-1890), it charts the emotional highs and lows of his stay in the Yellow House in Arles, and the times he spent in hospital after numerous breakdowns.

Peter Kennard: Archive of Dissent at the Whitechapel Gallery includes many of the artists’s most iconic political photomontages. Beginning in the 1970s, Kennard created images that by speaking truth to power, gave protest movements like CND (Campaign for Nuclear Disarmament), the Anti-Apartheid Movement and Stop the War Coalition the visual equivalent of marching songs.

It’s been a long time since the Whitechapel Gallery has presented three seriously good exhibitions at the same time. Already reviewed are Gavin Jantjes’ paintings on show in the main gallery. He is now joined, in gallery 2, by Dominique White, winner of the Max Mara Art Prize for Women and in galleries 5, 6 & 7, by Peter Kennard.

Ukraine’s history is complex and often bitter. The territory has been endlessly fought over, divided, annexed and occupied. From 1917-20 it enjoyed a brief period of independence before being swallowed up once more by the Soviet Union after a vicious three year war – an example that Vladimir Putin is copying with his monstrous invasion.

Belgian artist, Francis Alÿs has filled the Barbican Art Gallery with films of children playing games the world over. Many of them are familiar; they’re playing five stones in Nepal (pictured below left), conkers in London, stone skimming in Morocco, scissors/paper/stone and musical chairs in Mexico, hopscotch and leapfrog in Iraq, flying kites in Afghanistan and having snowball fights in Switzerland.
