851px x 315px is a performance that took place from 12th September to 1st November 2012. The work consisted in  collecting a series of images that accidentally fit exactly the dimensions of the Facebook cover (851px x 315px) by  looking at a period before the advent of the Facebook timeline. 

Lorusso highlights the boundaries that the interfaces of social media platforms impose on users and how these  dimensions shape one’s expression, as if it were an advertising banner. Additionally, the performance reflects upon  the construction of identity that takes place on dominant forms of social media, through a rejection of any personal  expression which is substituted by a set of rules such as picture dimensions and time.
