There were glass-treaded metal staircases inside that led to the upper projection room that showed a kaleidoscope of colors.Between the staircases was a seven-tiered cascading waterfall with underwater lighting. The interior had prisms producing colored rays from the outside sunlight.The floor-to-ceiling colored glass walls were mosaic. All this had the effect of a large crystal producing a large variety of colors.The frieze of the Glass Pavilion was written with aphoristic poems of glass done by the anarcho-socialist writer Paul Scheerbart.
