His main project is Weightless Sculpture, which he began in 1985 with the concept " A Line in Outer Space - Visible from earth - with the naked eye - At clear nights."This statement was sent to press-agencies worldwide in 1985. Christo was the first artist who gave his reaction. Soon after Harald Szeeman also sent a letter.Sjardijn made an animation at the Digistar Planetarium Computer in the Omniversum in The Hague and exhibited in the Municipal Museum of The Hague.One of his concepts is called ArtSpaceLab, which contains a virtual exhibition, a database and a proposal for an artproject inside the International Space Station. The virtual Coop Himmelb(l)au Pavilion gives access to a database, containing a big collection of free software and (video)tutorials as used by Sjardijn.
