The week in art

Works by Emil Cadoo, an arist once described by Edith Piaf as 'not a photographer, but a poet with a camera', have gone on show at the White Space gallery, London. Born in Brooklyn in 1926, Cadoo emigrated to Paris in 1960 and spent the next decade producing photo-essays on Duke Ellington, Ray Charles and James Baldwin as well as a celebrated series on Harlem street life. The exhibition, I Regret Nothing, is on until 6 May 2009 Photograph: Emil Cadoo/PR

Is Leonardo Da Vinci the only Renaissance artist to have a theme park created in his honour? The Château du Clos Lucé on the banks of the River Loire, where the artist lived for the last three years of his life, has already reinvented itself as a dedicated Da Vinci museum, but plans were announced this week to create the world's first 'intellectual and cultural theme park' devoted to the Renaissance polymath. Quite what this will entail is yet to be finalised but a life-size, mechanical robot lion designed by da Vinci expected to be a centrepiece in the 'Leonardo garden'.

Carnival and controversy on the streets of Havana this week as the city's 10th Biennial kicked off, with 300 artists and 54 countries taking part in the month-long visual arts festival. The theme this year is Integration and Resistance in the Global Age, and plenty of artists have used the opportunity to create works addressing globalisation and immigration, with one performance piece demanding the right to free speech on the island. The state-sponsored organisers of the biennial were not impressed, and branded the protestors 'people far removed from culture', misguidedly undertaking 'a provocation against the Cuban Revolution' Photograph: Claudia Daut/REUTERS

Also shaking things up this week was artist Gosha Ostretsov, who is Representing Russia at this year's Venice Biennale. Ostretsov released hundreds of anarchist texts attached to helium balloons across the streets of London while protesters gathered to demonstrate at the G20 summit. If you didn't manage to catch one, the artist is now exhibiting at Paradise Row gallery in east London. The Adventures of Robbing Good is on until 2 May 2009 Photograph: PR

This week artist Susan Collins launched her Seascape project, which presents over 30,000 images captured at five seaside locations across the south of England over the course of a year. The website acts as an archive for the main show, opening at the De La Warr Pavilion in East Sussex this weekend, in which digital works unfold in real time.

Madness lies at the Wellcome Collection this month, where a show on mental illness and the visual arts in turn-of-the-century Vienna has just opened. The multidisciplinary exhibition reveals anxieties about mental health and the mind, at a time when Sigmund Freud's ideas were rapidly gaining ground. Utopian psychiatric units, 'pathological portraits' and nervous ailments are explored by the curators.

A 14th-century glass bucket has sold for over £1.5m at Sotheby's in London. Elaborately detailed with coloured enamel, the eight-inch finger bowl was made during the reign of the Mamluk dynasty in Egypt, and passed around during meals attended by royalty. It went for almost twice the estimate, a fact Edward Gibbs, head of Islamic art at the auctioneers, ascribed to its 'quality and rarity' Photograph: Shaun Curry/AFP/Getty Images
