His work opened up the possibility for me to engage with photography as a process that is inclusive to my work in general and not just as it used to be as a documentary tool at the end of a project. His work is very much about the act of witnessing the shifting roles of material as their characteristics re-form in a forced combination of action and place. The photographic material, be it still or moving image, is the decisive point in his work as it brings the viewer into the process of his thinking and how he wants his viewers to see.


"Signer’s works have acquired the label ‘time-sculpture’. They share traditional sculpture’s concern with the crafting of physical materials in three dimensions, but they extend that concern into what may or may not be characterised as the fourth dimension: the dimension of time. Time-sculpture investigates the transformation of materials through time, focusing the viewer’s attention on the experience of the event, the changes wrought, and the forces involved. Variously combining three-dimensional objects, live action, still photography and moving-image documentation, Signer’s time-sculptures frame episodes of the containment and release of energy − always with ingenuity, often with captivating, epigrammatic swiftness and irresistible humour."
