This is a visualisation of the pile of PNG files that had not been used for at least weeks or years. Not just PNG files singularly, but imagine Adobe Photoshop; a program which includes adjustment layers, image layers, annotation notes, layer masks, keywords, file information, as well as other specific elements. How much data is it really taking up? How much of it is actually being used? Through these visualisations, experience a world that has been taken over by the PNG Grey Goo.
