The Primary Scientific Time Data (PSTD) artworks in this series originated from chance happenings and an unknown formula of putting things together. For example, Chris firstly selected a number of building materials and art supplies to work with. He added cement, building sand, plaster, industrial glosses, with acrylic, PVA and gloss paints. He was creating a mixture which was obscure and unidentifiable to his mind and hands. The last stage of making these artworks became more obvious as he used paint to pick out the transformations that had materialised in the mixture and the surface. Chris was in more control of his actions at this later stage. However, He had produced a system that operated through complexed decisions of adding and removing. He had designed a rebellious and improvisational technique achieved by dismantling and deconstructing materials, surface and a working process.
