On The Sidewalk is based on the exploration of human consciousness and the time-space relations between objects. Core samples from a range of locations, depths, and time periods — including cores from geological investigations, architectures, modern streets, and old Berlin cobble-stone pavements — were collected for this work. These core samples are then cut longitudinally into four pieces, to be reassembled separately in each sculpture and fastened with stainless steel hose-clamps. With the reassembly of these cores — and thus of the stories and the consecutive presents that they contain — time and space are mixed and compressed to form new arrangements with new dialogues between both geological and architectonical elements. Each sculpture functions as an avatar of a vertical geological timeline, stressing the idea of history as a human construction.
