The piece shown aboved was made with yarn and t pins.
Here's how Day describes his work:
Much of my work is derived from using universally accepted logics (i.e. fibonacci numbers and binary codes) and removing their logic by implementing a personal one. Through constant tweaks to these established understandings, my work takes form through knitted installations. These works are to be inviting for the viewer to climb through the extensions and find themselves surrounded by the piece itself.
My painting is, so far, a slow exploration. My interest at this moment is on the practice of painting large, larger than me anyways, pieces that I become invested in. Painting large is intimate by execution not on scale, which becomes largely time intensive.
