My work with glass responds to architecture, space, technologies and aspects of natural phenomena. Of critical consideration is the symbiosis between glass and light, and the ways in which glass absorbs, refracts and transmits light. With gravity as my main tool, I treat glass in a manner analogous to water and utilise its potential for shadow casting as the basis for conceptual idea development. Water and glass similarly cast a 3D or voluminous shadow due to the fact that light can transmit through it. When water or glass move with light the shadow becomes voluminous, supporting the notion that glass and water become a 4D material when activated by light.
