Lasact is a collaborative, interactive laser sculpture which was generated and formed involving the visitors of the Platine Festival during a four day period in August 2013 at the Helios light house in Cologne Ehrenfeld. With the aid of an easily accessible web app the recipients acted as collective performers that shaped a dynamic light sculpture en masse. Realized in collaboration with Daniel Becker, David Murmann, Alexander Rechberg and Adrian Rennertz.
