This glass prism was a gift to the ITC from the Canadian Baha'is. It is 9 panes of laminated glass about 2 meters high. Etched into it is the Greatest Name symbol which reflects onto the walls when the sunlight hits it right.

On the opposite side of this wall is the Counsel Chamber for the counsellors working at the ITC, and they have a sliding panel which can expose this prism. As the light hits it rainbows are spead throughout the chamber! What an inspiration!
