It’s a dirty job but someone has got to do it.
Visitors and passersby at Leeds’ Henry Moore Institute have rolled up their sleeves and mucked in - all in the name of art.
More than two tonnes of clay have been transformed into mini sculptures before they were flung onto the wall of the museum on The Headrow.
Shoppers in the city centre looked on as a whole manner of weird and wonderful creations were launched against the building.
The event forms part of an ongoing exhibition at the venue by Swiss-born New York-based artist Urs Fischer.
It is also part of the gallery’s The Event Sculpture which has seen the outside of the building becomes a site for art.
The Henry Moore Institute is part of The Henry Moore Foundation, which was set up by Moore in 1977 to encourage appreciation of the visual arts, especially sculpture.
