How to tell the story of one of the most infamous art forgery plots in history including a Manhattan gallery and a Chinese painter recreating around $80 million in abstract expressionists in a garage in Queens?

Polish theatre director Lukasz Twarkowski is taking almost four hours to do it and using four languages, video screens and "pumping techno beats" on the way.

His epic show ROHTKO, which is coming to London's Barbican art center in October, is inspired by the Knoedler scandal which brought down a venerable New York gallery and made fools of some of its richest collectors.

The case, which has already inspired a book and a documentary, saw the gallery close in 2011 after 165 years when it emerged it had sold around 40 fakes attributed to artists including Mark Rothko and Jackson Pollock.

ROHTKO runs at the Barbican from October 2 - 5.

The number of emojis currently available though more are expected to be added in an update in September. The rise of the emoji is examined in Pictograms: Iconic Japanese Designs at London's Japan House until November 9.

London gallery owner Sidonia "Sid" Motion told a court about her "unimaginable" ordeal after a stalker pleaded guilty to harassing her and her family.

Motion, who runs the Sid Motion gallery and is the daughter of former British poet laureate Andrew Motion and journalist Jan Dalley, was targeted by former art researcher Jordan Mearns, 40.

Mearns also harassed her partner, artist Charlie Billingham, spreading rumors about the couple and threatening them online.

The Times of London reported Motion told the Old Bailey: "The art world relies heavily on reputation and what Jordan was saying has been widely gossiped about. I will never get back my professional reputation or respect."

Mearns, who has been treated for mental health problems, was given a suspended sentence of 16 months and a ten-year restraining order preventing him from contacting Motion and her family and colleagues.

A huge Newell Convers Wyeth mural not seen for more than quarter of a century is going back on show in a specially-built new barn on his grandson's farm.

Jamie Wyeth told The New York Times he has spent about $1 million installing the 60-feet-long and 19-feet-high work called Apotheosis of the Family on his farm in Wilmington, Delaware.

It had hung for 75 years in the offices of the Wilmington Savings Fund Society, the bank that commissioned it, but was taken down in 1998 and given first to the local historical society then the family foundation.

Work has been carried out to restore the mural, which was at one point rolled up tightly damaging the canvas, and it is expected to go on show later this year with visitors able to book to see it via the nearby Brandywine Museum of Art.

1 - The Dallas Museum of Art has appointed Brian Ferriso as its next director to succeed Agustín Arteaga who stepped down in December after eight years in charge. Ferriso starts on December 1 and is expected to lead the museum through a $150 million revamp, having raised a similar amount in his last job in charge of the Portland Art Museum in Oregon.

2 - Frieze has launched a new $13,400 prize for artists working in "non-traditional media and unconventional forms" ahead of its London fair in October. The prize also includes a commission for the Nicoletta Fiorucci Foundation’s Library.

3 - Owners of empty properties could get tax breaks for renting them to artists under plans being looked at by local politicians in Sydney, Australia. The proposals to bring more affordable art spaces back to the city could also see property owners hit with a "lazy place tax" where they are charged more if a building stands empty.
