This is the first European solo show by the renowned, Pakistan-born Nalini Malani. Extending her involvement with figurative painting into other media including video and installation, Malani always retains painting's inventive fluidity. Fragmented images are turned into close to a 3D collage. The evocative mix builds a series of metamorphic narratives. Hers is a dream of east and west, of myth and reverie. Here she tackles Euripides' Medea, the Goddess Sita from the Ramayana and Alice from Alice In Wonderland, all on adventures in a world curtailed by domestic or fundamentalist convention.RC  · Irish Museum Of Modern Art, Wed 11 to Oct 14  Amy Sharrocks is on a mission to get us in the water. On Thursday, she is inviting the public to join her in celebrating our city's waterways in a marathon swim across London. At 6am she's at Tooting Bec Lido from where she will go through south London's leisure centres to the Serpentine and finish in Hampstead Heath swimming ponds at 7pm. Sharrocks says she was inspired by the film The Swimmer starring Burt Lancaster as the suburbanite on his odyssey through the backyards of upstate New York. Whether Sharrocks will encounter the same hedonism, nudism and alienation remains to be seen. Models in kaftans drinking Martinis in Camberwell Leisure Centre seems unlikely, but then, Peckham is full of surprises.JL  · Various venues, Thu 12, www.iwanttoswim.co.uk  Before starring in this autumn's prestigious Istanbul Biennale, the French artist Alexandre Perigot brings his mystifying architectural installations to Tramway. Perigot's sound and sculptural works tackle contemporary mythmaking, propaganda and our sense of social responsibility. Here for instance is Maison d'Elvis, a giant replica of Graceland filled with haunting performances including the Glasgow choir The Parsonage's rendition of Elvis's If I Can Dream, in tribute to Martin Luther King, a piece by composer Simon Fisher Turner. In the accompanying installation Sometimes You Win Sometimes You Lose it's as if the very gallery walls are full of questioning whisperings.RC  · Tramway, Sun 8 to Aug 5  Social SystemsNewlyn, Penzance, St Ives  The artists in this Cornish art event have a similar artistic approach, each relying on input from the general public. German artist Regina Möller is known for publishing her Cosmopolitan parodies, lo-fi glossies about fashion, sex and housekeeping that challenge perceptions of women. She has produced a special one-off about Cornwall that will be available from the three galleries taking part in this ProjectBase show. Christine Borland is currently resident artist at Peninsula Medical School, and her explorations into the science world will be exhibited at the Newlyn Art Gallery. At Tate St Ives, the Danish collective Superflex source free access to software, while the Buenos Aires team Eloisa Cartonera distribute unpublished works by Cornish writers at the new Exchange space in Penzance. JL  · Newlyn Art Gallery, Newlyn; The Exchange, Penzance; Tate St Ives, St Ives, Sat 7 to Sep 2  Staged across two towns, this show questions what it means to be English. In Sunderland Immo Klink's photographs deal with surveillance, The Agents Of Change propose recycled furniture and The Space Hijackers go in for "Guerrilla Benching". Down in Southampton, Jane Chavez-Dawson's film maps English B&Bs and Samar Asamoah's Greenhouse is inscribed with Islamic symbols, plus, at all six venues, Susan Diab sings Oh I Do Like To Be Beside The Seaside in Arabic.RC  · Northern Gallery For Contemporary Art/National Glass Centre/Reg Vardy Gallery, Sunderland; John Hansard Gallery/Millais Gallery/Southampton City Art Gallery, Southampton, to Sep 22  Vauxhall Art Car Boot FairLondon  The art bargain of the year is upon us and you will need kneepads and deep pockets for this boot sale scrum. Forget the usual wading through other people's trash, this event offers Peter Blakes, Tracey Emins, Gavin Turks and many more art stars too dear to mention humbled to rock bottom prices in the name of fair play. Last year you could pick up a plaster cast of a rich tea biscuit by Turk for the price of a cuppa and dunk it in a Sarah Lucas mug. This year those chaps at Vauxhall have invited four artists to customise their cars. Peter Blake has written excerpts from Kerouac's on the road all over his, while Ian Monroe, master of the vinyl abstract, has transformed one into a magic eye trick. If that doesn't entice, then you might prefer the cocktail girls dispensing their elaborate concoctions. For once, a couple of gin slings won't affect your shopping powers. There's no such thing as a rash purchase here. JL  · Old Truman Brewery, E8, Sun 8  It's that winning combination of geeky enthusiasm and irony that makes Jamie Shovlin's art so entertaining. His new exhibition features a map of the US listing the dreams of Playboy centrefolds pinned to their home towns. The show is inspired by the history, politics and culture of mid-20th century America. Reworking the albums among his parents' record collection, Shovlin offers alternative versions of the albums of Bob Seger, Hall & Oates and the Eagles and he also highlights newsworthy events that defined the 1960s and 1970s including the Manson killings and Woodstock. With a smattering of references to 1960s artists Lawrence Weiner and Ed Ruscha, Shovlin romanticises an era he clearly wished he'd been alive for. JL  · Haunch Of Venison, W1, to Aug 18  Bruce Lacey is often referred to as one of Britain's most renowned eccentrics, but he is more than that: he is an artist of rare individualistic and innovatory spirit. Here's evidence, in sculptures, films and robots of more than half a century of irreverent mayhem. Lacey revived the anarchic spirit of dada and helped to start a libertarian cultural climate that would take off in the mid-60s. Lacey's CV includes work with the Goons, the Beatles, Ken Russell, and Andrew Logan, but few collaborators could ever match his creative idiosyncrasies. Still coming on loony and strong at the age of 80, Lacey is these days working on his "vox humana exploration" - performances which involve filtering renditions of Rod Stewart and Queen classics through distorting gadgetry. And if you're around, don't miss a live Logan performance on the evening of Jul 21.RC  · Norwich Arts Centre, to Aug 4
