Shadow Mask presents a theatrical scene made atmospheric by how it is lit. Special effects are a common tactic in both art and technology. For many decades a simple metal grill, perforated with tiny holes, was part of the cathode ray tube of the original television. This shadow mask was the mechanism of filtering and controlling how red, green and blue (RGB) electron beams would land on a phosphorus coating on the inside of the screen, agitate it and then magically create the picture before your eyes.
