Julian Bond built this physical casting machine, which can be used as a re-configurable mold to cast ceramic objects:
Slip casting molds are usually fixed. Each new design needs a new mold to be made. This project was about giving anyone the ability to engage with the slip casting technique and allowing them to create a one off design. The machine is designed to engage with the user allowing them to understand the form they are creating. This is a rapid manufacturing tool, not rapid prototyping, each piece that is made can be fired and glazed and used as a final product.
Quick, someone hook it up to a computer to make the slowest video game display ever! [via dudecraft]
