The display consists of 568, two-metre LED tubes hanging throughout Covent Garden area. But this hall the South Hall it is actually interactive and you can operate it be simply putting your hand on the panel here and as you can see up there I am spawning 'snow' with my hand like this. So as I move my hand down I am actually creating 'snow'."

Covent Garden has a programme of events, including musical performances, to go with the installation.
