All the important principles of Fog Screen technology have been patented. The basic components of the screen are a laminar, non-turbulent airflow, and a thin fog screen (or any particles) injected into and inside a laminar flow. Created this way, the fog screen is an internal part of the laminar airflow, and remains thin, crisp, and protected from turbulence. When the screen is formed, images can be projected onto it. The screen can be translucent or fully opaque. The quality, size, and other features of the screen have been thoroughly improved in our latest prototype which was shown in Siggraph.
The fog is made in the device from water using ultrasonic waves. The fog is thus not hot, but feels cool, an does not make your hand wet if you hold it in the fog flow, the fog feels dry.
When the device is rigged up, it generates a mild downwards air and fog flow.
