Austrian artist Florentina Holzinger has skated straight into controversy after her work Crash Pipe was launched with a performance by naked female skaters.

The work, a skateboarding halfpipe made from eight tons of metal, was installed outside Hanover's historic Artists' House at the end of last month.

Holzinger, who will represent Austria at this year's Venice Biennale, came in for criticism after joining three other female skaters at the launch wearing nothing but kneepads and skates.

Among the complaints logged by the local newspaper, Hannoversche Allgemeine Zeitung, were a lack of male skaters in a similar state of undress and the loss of car parking space.

She was backed by the city's art center which promoted the work and said it was intended to reflect "current debates about the use of urban space".

The family of Japanese-American artist Ruth Asawa has set up a permanent exhibition space dedicated to her life and work in her native San Francisco.

Rotating exhibitions of her work as well as some by friends and contemporaries including Josef and Anni Albers and Imogen Cunningham will feature alongside an annual exhibition for students and faculty from the city's art school that bears her name.

The building in the Dogpatch neighborhood opens on May 9 with a show co-curated by her daughters.

Her grandson Henry Weverka said the move was inspired by his grandmother's work as "an individual artist" and as a "tremendous advocate for the arts and arts education in the Bay Area".

Asawa, who died aged 87 in 2013, was born in California to Japanese immigrant parents and spent her teenage years held in internment camps after the USA declared war on Japan following the attack on Pearl Harbor.

She created several public art commissions in San Francisco, including fountains at Ghirardelli Square and Union Square, and the Japanese American Internment Memorial in San Jose. A major exhibition of her work has just opened at the Guggenheim in Bilbao.

Award-winning architect Kengo Kuma has been accused of adding a "concrete UFO" to a medieval French cathedral.

The Japanese designer's $6.36 million 450-tonne concrete gallery at the Saint-Maurice Cathedral in Angers has the official seal of approval - it is due to be opened on Thursday by culture minister Catherine Pegard - but not everyone is convinced.

Regional newspaper Ouest-France described it as looking like a "reinforced concrete UFO" and said locals cannot decide if it is an "architectural jewel or a wart".

Kuma, who designed Tokyo’s Olympic stadium and the Nezu museum, said the gallery which was built to help preserve a series of sculptures dating back as far as the 12th century was an attempt to "create a harmonious dialogue between a contemporary creation whilst preserving Middle Age architectural heritage".
