If they remember the 1960s at all, the ageing population of Bexhill-on-Sea will remember Bridget Riley for her black and white experiments in perception. The iconic results of this line of enquiry can still result in a “happening” for the eyeballs. And that’s exactly what you get from the earliest paintings in this show: uniform stripes of black and white that won’t for a moment stay still. 

For all the wrong reasons, the work of Dexter Dalwood serves as a useful metaphor for this exhibition. Trite, tokenistic and desperate to look clever, Dalwood’s paintings are as tiresomely inward-looking as the show itself, which is a dismal example of curatorial self-indulgence at the expense of public engagement.

A steel corridor stretches as far into the distance as you can see (pictured below right); the gleaming sides and gently sloping floor invite you to step inside but, as you venture further in, it gets darker and darker until you are groping your way in pitch blackness. This unnerving experience reminded me of when, as a child, I followed my parents deep into the cliffs of north Cornwall as they gingerly crept along disused mine shafts, lighting the way with matches that quickly fizzled out.

Enzo Green, Shirim, Raethro Red, Raemar Magenta. Everything has a name. But beyond the meaningless but musical sounds of their titles, the light projections and installations on view at Houghton Hall by the leading American light, land and skyscape artist James Turrell are an ineffable art whose presence and effect is subtle, substantial, utterly memorable and almost beyond words.  

It's impossible to overstate the reverence accorded the painter Agnes Martin by her fellow artists; in the panoply of American cultural goddesses, she is right up there with Emily Dickinson. Yet she is scarcely known in the wider world, partly because her work is relentlessly abstract, but also because she was deliberately evasive.

Imagine if broadcasters thought the only living pop star worth giving air time to was Lady Gaga. Imagine – the horror. It would be wall-to-wall Gaga for the foreseeable future. And then imagine if the only living contemporary artist commissioning editors at Channel 4 and the BBC even bothered looking at was… Grayson Perry. Imagine. 

The country is groaning under the weight of commemorations, exhibitions, publications and programmes all marking significant anniversaries of World War One, but the underlying message – lest we forget – remains as potent as ever, perhaps even more so in these tumultuous times.

Glasgow-based Corin Sworn is the fifth winner of the Max Mara Art Prize for Women. Every two years a British artist is chosen on the basis of a proposal, rather than existing work. The fashion house then supports the project with funding, a bespoke, six-month residency in Italy and, following the Whitechapel Gallery show, an exhibition at the Collezione Maramotti in Reggio Emilia, where the HQ of the family-run business is located.

What strange things netsuke are. Tiny sculptures, usually made from wood or ivory and depicting anything from figures, to fruit to animals, they were first made in the 17th century as toggles to attach pockets and bags to the robes worn by Japanese men. For as long as they have existed they have been considered highly collectible, and perhaps it is this, and the rapturous appreciation they inspire in their devotees, that to me at least makes them seem hopelessly, unspeakably kitsch.

I had never really photographed landscape. But I spent many wonderful weekends in Suffolk and Norfolk along the coast. This project began when I just decided to photograph the sea in a very abstract way. The sky and the light and the flatness were quite inspiring for me.
