Artist Alessandro Lupi seems to capture ghosts in his eerie sculptures. Lupi begins with simple thread to create his artwork. He paints each strand one at a time with fluorescent paint. The threads are then arranged and lit with black lights. Lupi often arranges the thread in the form of a figure – a person that at once seems to inhabit a space and in the process of disappearing. He calls his work ‘Fluorescent Densities’. The designation alludes to the way he uses his medium to “investigate” and play with light and space.
