The cloud is a spectre, hauntingly present yet intangible. It knows you intimately: your memories, work, shopping habits, medical records, bank account details. It knows your likes, your friends, where you are and where you've been, the pace of the strides you took along the way. Though this friendly ghost is at hand wherever and wherever, it is also strangely absent, dispersed between servers, neither here nor there and everywhere. Wireless devices enable a seemingly ubiquitous yet limited view of the vaporous leviathan. Analysing the materials of the gadgetry used to tap in to the atomised data, breaking down a smartphone to its elemental composition, Cloud Harvest takes steps to locating the cloud in the materials it is channeled through.
