The Barbican have commissioned Argentinian artist Leandro Erlich to create a 3D optical illusion.
'Dalston House' looks exactly like a regular Victorian building. But it's not. It's really just a reflection.
The facade lies 'horizontally on the ground with mirrors positioned overhead'.
This means that to the viewer, participants appear to be climbing up the walls, Spiderman-style.
The installation runs from 26 June 2013 - 4 August 2013.
