Exhibit: Persistence of Vision, LED Video
Venue: Sharjah Science Centre
Location: Sharjah, United Arab Emirates
Date: October, 1995
Client: Ontario Science Centre
Contributors: Mystus Interactus, Ontario Science Centre (housing)

Client Requirements:
Persistence of vision in the human eye is demonstrated by scanning an image through a single line of bright, fast-response lights. During these eye movements, the image is effectively wiped across the retina and the full image is perceived. The Ontario Science Centre commissioned Mystus Interactus to create a display with the above characteristics as well as the ability to toggle into a "teach mode" to give visitors a better sense of what is happening. The visitor also needed to be able to flip through eight different images.

Mystus Expertise:
Mystus achieved the objective by creating a large array of lights that could function in "single line" mode to show the effect or in "full array" mode to display the image in more detail.

Mystus completed the following:
· The prototype, design and fabrication of a 64 x 80 LED display (19 x 22 inches)
· Manufacturing a custom-printed circuit board
· Programming the controller and installing long-range visitor input buttons

Unique Features:
A duplicate exhibit was commissioned for the Thailand Science Centre in January, 1997.
