Robert De Niro has described it as "intense": it's 6x9, The Guardian's first virtual reality experience, which invites you to don VR goggles, step into a 'cell' and experience life in a US solitary confinement prison cell.
The experience — which won plaudits at the Sundance and Tribeca film festivals and is also available on Google Cardboard — gives you a disturbingly visceral idea of what it's like spending 23 hours a day in a cell measuring 6x9 feet for days, weeks, months or even years at a time.
We checked out the experience at a virtual reality fair in Greenwich earlier this year, and can tell you that things get trippy and disconcerting as you begin to float around the cell, and start 'seeing things'.
6x9 is open at The Guardian's offices, Kings Place, 90 York Way, King's Cross, N1 9GU on 25-27 May and 1-3 June from 1pm-8pm. Entry is free, but expect a queue.
