Ron Arad's Curtain Call uses 5,600 silicon rods to create a 360 degree projection screen in London's Roundhouse venue. Arad has invited some of his favourite artists to create work for the piece

Arad created the piece as part of the Bloomberg Summer at the Roundhouse season of events. The installation encloses an 18-metre in diameter space - visitors sit in the middle to enjoy a daily reel of works by a roster including animator/designer Javier Mariscal,

fashion designer Hussein Chalayan

Greenaway & Greenaway, whose piece references the Roundhouse's architecture

and Gabriel and Shira Klasmer, whose abstract graphics are among the more effective pieces.

My favourite and yes I'm aware that he divides opinion on this blog, is David Shrigley's Walker in which a hairy, booted figure stomps miserably around the room, pausing briefly to let out a heartrending moan, before renewing his never-ending journey.

There will also be a variety of special events in the space. Curtain Call is on until August 29. More info here. Arad's studio blog on the project is here
