This installation is made of more than 150 pieces that they are attached to the wall. This art work was presented on Valiasr Street in Tehran by the name of “Conversion”. I placed it in a dark space so the moment that audience come close to the installation, images began to unfold by using a video projection. And when the audience left the space, it became dark again. By using video mapping technics and also fading in and out the images on the installation, I tried to share and present the meaning of time and conversion to the audience.
