Interlocking kilnformed glass . These wall panels are a demonstration of how technology enables an complex form to be cut in glass. This shape could not be cut as cleanly or as accurately without waterjet. Two piece of glass interlock together to give this simple just complex zip form. These panels can be made to order and to a colour of choice. Personally, the white on a strong coloured wall looks very effective. An example of complexity and simplicity in glass.
